土木工程专业英语翻译第一篇:土木工程专业英语翻译1.第一课土木工程,这个最古老的工程专业,是指对被建设环境的规划、设计、建筑和管理。
这个环境包括按科学原理所建的一切结构,从灌溉和排水系统到火箭发射设备。
土木工程师们修路、建桥、打隧道,木工程师始终(将介词throughout转译成副词)都要充分利用计算机。
用计算机来设计工程的各要素(计算机辅助设计CAD)且用计算机来管理这个工程项目。
对于现代土木工程师而言,计算机是必备的工具,因为它们允许工程师高效建水坝,海港,发电厂,供水排水系统,建医院,学校,公共交通设施和其他公共设施实质上就是要建设现代化社会和大量人口集中地。
他们也建设私有的设施,例如:机场,铁路,管线,摩天大楼,和其他大型建筑物,它们设计用于工业,商业和居住等用途。
此外,土木工程师规划,设计和建设完整的城市和乡镇,近年来,已经在规划和设计空间平台来构建自给自足型社区。
2.土木这个词来源于拉丁文,原意是市民。
1782年,英国人JohnSmeaton用这个术语将非军事工程工作从在当时占绝大多数的军事工程师所人事的工程工作中区别开来。
从那以后,土木工程这个词常常用于表示建设公用设施的工程师们所人事的工作,尽管这个领域要宽广得多。
3.范围:因为它的面太广,所以土木工程被分成许多技术专业。
各专业的土木工程专家所需要的技能取决于工程项目的类型。

第一单元In terms of architecture, the structure of a building is and does much more than that. It is an inseparable part of the building form and to varying degrees is a generator of that form. Used skillfully, the building structure can establish or reinforce orders and rhythms among the architectural volumes and planes. It can be visually dominant or recessive. It can develop harmonies or conflicts. It can be both confining and emancipating. And, unfortunately in some cases, it cannot be ignored. It is physical.从建筑学方面来说,建筑结构并非仅仅如此,它是建筑风格一个不可分割的部分,并且在不同程度上体现了建筑风格。
巧妙熟练地设计建筑结构能够在建筑空间和平面上建立或加强格调和韵律。
它做到直观上的显性和隐形,能够发展和谐体或对照体,同时它是局限的和开放的,并且在(某些情况下)一点是不可忽略的,也就是它的实际性。
The requirement of strength means that the materials selected to resist the stresses generated by the loads and shapers of the structure(s) must be adequate. Indeed, a “factor of Safety” is usually provided so that under the anticipated loads, a given material is not stressed to a level even close to its rupture point. The material property called stiffness is considered with the requirement of strength. Stiffness is different from strength in that it directly involves how much a structure strains or deflects under load. A material that is very strong but lacking in stiffness will deform too much to be of value in resisting the forces applied.强度要求意味着选择合适的材料来承受由荷载引起的应力和保持适当结构形状。

第一单元Fundamentally, engineering is an end-product-oriented discipline that is innovative, cost-conscious and mindful of human factors. It is concerned with the creation of new entities, devices or methods of solution: a new process, a new material, an improved power source, a more efficient arrangement of tasks to accomplish a desired goal or a new structure. Engineering is also more often than not concerned with obtaining economical solutions. And, finally, human safety is always a key consideration.从根本上,工程是一个以最终产品为导向的行业,它具有创新、成本意识,同时也注意到人为因素。
它与创建新的实体、设备或解决方案有关:新工艺、新材料、一个改进的动力来源、任务的一项更有效地安排,用以完成所需的目标或创建一个新的结构。
工程是也不仅仅关心获得经济的解决方案。
最终,人类安全才是一个最重要的考虑因素。
Engineering is concerned with the use of abstract scientific ways of thinking and of defining real world problems. The use of idealizations and development of procedures for establishing bounds within which behavior can be ascertained are part of the process.工程关心的是,使用抽象的科学方法思考和定义现实世界的问题。

外文翻译学院:城市建设学院专业:土木工程学号:200808141156姓名:郭占勇指导教师:陈伟武汉科技大学2012年月日Discuss the construction temperature and crack of theconcrete lightlyBy G. K. Kululanga, W. Kuotcha, R. McCaffer, Member, ASCE, and F. Edum-Fotwe ,The American Society of Civil EngineersThe summary Through observation live for many years, through consulting the monograph about stress within the concrete, explain to concrete temperature reason , on-the-spot concrete control and measure , prevention of crack of temperature that crack produce.Key word;Concrete;Temperature stress;Crack;Control1. The concrete occupies the important position in modern engineering construction. But today, the crack of the concrete is comparatively general, the cracks are nearly omnipresent in the science of bridge building. Though we take various kinds of measures in constructing, careful, but the crack still occurs now and then. Tracing it to its cause, it is one of them incompletely that our change to concrete temperature stress pays attention to. In the large volume concrete, temperature stress and temperature control are significant. This is mainly because of the reason of two respects. First of all, concrete often appear the temperature crack in not constructing, influence the globality and durability of the structure. Secondly, in the course of operating, the temperature change has remarkable influence that can't be ignored on the stress state of the structure. We meet to construct temperature crack in mainly, so only to origin cause of formation and treatment measure, concrete of crack make a discussion in constructing this text.Reason of a crackHave many kinds of reasons to produce the crack in the concrete, it is mainly the changes of temperature and humidity, fragility and disparity of the concrete, and the structure is unreasonable, the raw materials is not up to standard (if the alkali aggregate react), the template is out of shape, the foundation does not subside etc. evenly . The cement emits a large amount of heat of hydration when the concrete is hardenned, inside temperature is rising constantly, cause the stress of drawing on the surface. In the course of lowering the temperature , is it congeal foundation pay restrain to mix always later stage, will present the stress of drawing within the concrete . Reducing of temperature can surface cause heavy stress of drawing very in concrete too. When these draw the stressand go beyond resisting the ability of splitting of concrete , namely will present the crack .A lot of inside humidity of concrete change very light or change relatively slow, surface humidity might change heavy the violent change takes placing. Such as maintaining thoroughly, when getting wetter when not doing,contract surface there aren't deformation doing, often cause the crack too. The concrete is a kind of fragility material , tensile strength is about 1/10 of the compression strength, is it carry on one's shoulder or back limit when draw out of shape to have *104 only , is it carry on one's shoulder or back limit location when stretch out of shape to there is *104 to add for a long time to add a short time. Because raw materials even, water dust than unstable, transport and build phenomenon of emanating of course, its tensile strength is not even in the same concrete, a lot of resist the ability of drawing very low, it is apt to present the weak position of the crack. Among armored concrete , draw stress to undertake by reinforcing bar mainly , concrete bear stress of keeping just. Or reinforcing bar mix if edge position gone to to congeal present the stress of drawing in the structure in plain concrete, must rely on the concrete oneself to bear . Require to avoid the stress of drawing or only very small stress of drawing appears of the the general design. But the concrete is cooled from maximum temperature to the steady temperature of operating period in constructing, often cause sizable to draw the stress within the concrete. The temperature stress can exceed other outsides and load the stresses caused sometimes, know change law , temperature of stress for carry on reasonable structural design and construct extremely important.Analysis of 2 temperature stressesCan be divided into following three stages according to the forming process of the temperature stress:(1)It is early: Build concrete is it is it over basically to send out heat to cement to begin , generally one one day by oneself. Two characteristics at this stage, first, the cement emits a large amount of heat of hydration, second , mix and congeal the changing sharply of elastic model quantity. Because of the change of elastic model quantity , form the remaining stress in the concrete in this period.(2)Middle period: Up till the concrete is cooled until stability temperature from cement send out heat function basically when expiring, in this period, the temperature stress is mainly because the cooling of the concrete and external temperature change cause, these stresses and remnants stresses that is formed in early days are superposed , mix and congeal the elastic mould amount that goes to and does not change much during this period.(3)Later period: Operation period after the complete cooling of concrete. Temperature stress whether external temperature change cause mainly, these stresses andfirst two kinds of remnants stresseses are changed and added .Can be divided into two kinds according to the reason why the temperature stress causes:(1)Spontaneous stress: There are not any restraint or totally static structure at the border, if inside temperature is non-linear distribution, temperature stress appearing because structure restrains from each other. For example, the body of mound of the bridge, the physical dimension is relatively large, surface temperature is low when the concrete is cooled, inside temperature is high, present the stress of drawing on the surface, present the stress of pressing in the middle.(2)Restrain the stress: All of the structure ones or it restrain external one some border,can't out of shape and stress not cause not free. Such as case roof beam roof concrete and guardrail concrete.This two kinds of temperature stresses draw back stresses caused to act on with the doing of concrete together frequently. It is a more complicated job to want to analyse the distribution , size of the temperature stress accurately according to known temperature. In case of great majority , need to rely on the model test or the number value to calculate. To is it make temperature stress have sizable limp to creep concrete, at the stress accounting temperature, must consider the influence that creep , calculate concretly that no longer states thinly here.Control and preventing the measure of the crack of 3 temperatureFor prevent crack , lighten temperature stress can from control temperature and is it is it set about to restrain terms from two to improve.The measure of controlling temperature is as follows:(1)Is it improve aggregate grade mix , is it do rigid concrete to spend , mix mixture to adopt, is it guide angry pharmaceutical or plastification pharmaceutical ,etc. measure in order to reduce cement consumption of concrete to add;(2)Add water or the water to cool the broken stone in order to reduce the temperature of building of the concrete while mixing and shutting the concrete;(3)Reduce the thickness of building while building the concrete on hot day, utilize and build the aspect to dispel the heat;(4)Bury the water pipe underground in the concrete, enter the cold water to lower the temperature openly;(5)Stipulate rational form removal time, the temperature keeps warm the surface while lowering suddenly, in case that the rapid temperature gradient takes place in the concrete surface;(6)The concrete with medium and long-term and exposed construction builds a pieceof surface or thin wall structure, take the measure of keeping warm in cold season;The measure of improving condition of restraining is:(1)Divide and sew and divide one rationally ;(2)Prevent the foundation from rising and falling too big;(3)Rational arrangement construction process, prevent the too big discrepancy in elevation and side from exposing for a long time;In addition, improve the performance of the concrete and improve and resist the ability of splitting, strengthen maintenance , prevent the surface from being done and contracted , especially guarantee the quality of the concrete is very important to preventing the crack, should pay special attention to avoiding producing and running through the crack , the globality resumed its structure after appearing is very difficult, so should rely mainly on preventing the emergence of the running through crack while constructing.In construction of concrete , for raise turnover rate of template , demand concrete form removal as soon as possible that build newly often. Should consider form removal time properly when concrete temperature is higher than the temperature, so as not to cause the superficial early crack of concrete. Building the early form removal newly, cause very large stress of drawing on the surface, the phenomenon that " temperature is assaulted " appears. Build initial stage in concrete, because heat of hydration is sent out, the surface causes sizable to draw the stress, surface temperature is also higher than temperature at this moment, remove the template at this moment , surface temperature is lowered suddenly, must cause temperature gradient , thus add and draw the stress on the surface , change and add with the heat of hydration stress, in addition, the concrete dries and contracts , the superficial stress of drawing reaches very great number value, have danger of causing the crack, but cover a light-duty heat insulator with on the surface in time after removing the template , for instance foam sponge ,etc., for prevent concrete surface from produce the too big stress of drawing, have remarkable results.Add muscle influence to large volume temperature stress of concrete very light , because large volume concrete include muscle to be rate very much low. Just have influence on the general armored concrete. On terms that temperature is not very high and the stress is less than limit of surrendering, every performance of the steel is steady, and have nothing to do with stress state , time and temperature. Line bloated coefficient of steel and concrete line bloated coefficient difference very light, take place little internal stress very only between the two while changing in temperature. Because elastic mould amount of steel concrete elastic mould 7~15 of quantity, reach as interior concrete stress tensile strength and when fracturing, the stress of the reinforcing bar will not exceed10000kg/cm2. . So is it is it prevent tiny appearance difficulty very much of crack from to make use of reinforcing bar to want among concrete. But the crack in the structure generally becomes numerous, the interval is little, the width and depth are smaller after adding the muscle. And if diameter of reinforcing bar detailed and when interval dense, to improve concrete resist result of person who split better. Concrete and surface , armored concrete of structure can take place detailed and shallow crack often, among them the great majority belong to and do and draw back the crack. Though this kind of crack is generally all relatively light, it stills have certain influence on the intensity and durability of the structure.In order to guarantee concrete project quality , prevent fracturing , improve the durability of the concrete, use the admixture to reduce one of the measures that fractures correctly. Whether is it reduce water is it split pharmaceutical to defend , I summarize his main function in practice to use.(1)There is pore Dao of a large number of mao in the concrete , produce capillary tension in the capillary after water is evaporated, make concrete is it contract out of shape to do. Increasing the thin aperture of hair can reduce the capillary surface tension , but will make the intensity of concrete reduce . This surface tension theory has already been confirmed in the world as far back as the sixties.(2)Water dust than influence important factor that concrete shrink, is it reduce water is it split pharmaceutical can make concrete water consumption reduce by 25% to defend to use.(3)Cement consumption important factor, concrete of person who shrink too, is it add and subtract water is it split concrete reducible 15% of the cement consumption on terms that keep the intensity of concrete of pharmaceutical to defend to mix, its volume is supplemented by increasing aggregate consumption.(4)Reduce water is it split pharmaceutical can improve consistency of grout , reduce concrete secrete ink to defend, reduce and sink and draw back deforming.(5)Improve glueing the strength of forming of the grout and aggregate, the concrete improved resists the performance of splitting.(6)Concrete is it produce stress of drawing to restrain from while shrinking, crack when drawing the stress and is greater than concrete tensile strength can produce. Reduce water is it split pharmaceutical effective concrete tensile strength of improvement very to defend , improve resisting the performance of splitting of concrete by a wide margin.(7)It can make the concrete density good to add the admixture to mix , can improve resisting carbonization of concrete effectively , reduce carbonization to shrink.(8)Is it reduce water is it split slow coagulation time proper concrete underpharmaceutical to defend , on the basis of preventing the fast water of cement from sending out heat effectively to mix, prevent the plasticity shrink that brings because the cement is not congealed for a long time from increasing.(9)Mix admixture concrete and getting easy and kind , surface easy to feel flat , form little membrane, reduce the moisture to evaporate, reduce drily and shrink. A lot of admixture all have the functions of slow coagulation , increasing and apt , improvement plasticity, the experiment that we should carry on in this respect more in the project practice is compared with and studied, than lean against not improving terms more simple,may getting simple and more direct, economy.Early maintenance of 4 concretePractice has proved , the common crack of concrete , most is the surface crack of different depth, main reason its whether temperature gradient cause cold temperature of area lower too easy to form crack suddenly. So say the warm - keeping of the concrete is especially important to preventing the early crack of surface.From the viewpoint of temperature stress, should reach and require to keep warm followingly:1)Prevent concrete internal and external temperature poor and concrete surface gradient from , prevent the surface crack.2)Prevent concrete from to be ultra and cold , should is it is it make the minimum temperature is not lower than the steady temperature of concrete service time construction time in concrete to try to try one's best.3)Prevent the old concrete subcooling , in order to reduce the restraint among the old and new concrete.The early maintenance of the concrete, the main purpose lies in keeping the suitable warm and humid condition , in order to get the result of two respects, on the other hand make the concrete avoid the invasion and attack of the unfavorable and warm , humidity out of shape, the ones that prevent from harmfully are cold to contract and do to contract. On one hand make cement water function go on smoothly , is in the hope of reaching the intensity designed and resisting the ability of splitting.The suitable warm damp condition is interrelated. Mix warm - keeping measure paid to congeal often protect wet results too. Analyse , water concrete include moisture can meet demand , cement of water have enough and to spare newly theoretically. But because the reason of evaporating etc. often causes losses of the moisture, thus postpone or hinder water of the cement from, the surface concrete receives this kind of adverse effect easiestly and directly. Key period when maintained in initial a few days after so the concrete is built, should pay attention to conscientiously in constructing.ConclusionsConstruction temperature and relation of crack in concrete the above carry on preliminary discussion of theory and practice, though the academia has different theories to origin cause of formation and computing technology of the concrete crack, but to concrete prevention and improving the measure suggestion to relatively unify , application in practice result fine too at the same time, concrete to is it observe , compare more more by us to want in constructing, analyse more , summarize more after going wrong , combine many kinds of prevention and deal with the measure, the crack of the concrete can be avoided.2.Quality control of waterproof concrete constructionCombined with experience, from formwork design, fabrication and installation, assembing reinforoement, pouring and curing of concrete and other aspects construction technology of fair-faced concrete is introduced as well as quality control measures and standards in order to reduce engineering cost to acquire satisfied economic and social benefits.The factors of influening waterproof- concrete quality are very manyAny links does not pay attention to the water-proof concrete of field loss hinders the water function without exception jointly with degree.Engineering construction in the basement adopts secondary form board fabrication and installation, reinforced bar fabrication and bind, concrete stirring and mixing system and transport, concrete concrete covibration beat with a stick, construction joint practice, concrete curing and dismantle model and beingready for backfill and so on aspects.These are very critical to quality method to ensure that water-proof concrete self water-proof, and the way of practice has wan out.Method being under construction2.1 Fabrication and InstallationAccording to the concrett of closely knit , demand of reason why to form board since the water-proof also concrete have made and have assembled corresponding rise is special , be to require that not leaving out thick fluid , firm closely knit block of wood deformation , water absorption Character should be small and ought to give priority to select and using bamboo slab rubber form board or the steel form.. Strict control form board room gap size, necessary exceeding 2 mms uses foam rubber or plastic to squeeze a crack in , porous form board nonutility without exception to board face Be ready for wall post at the same time rotting the prevention and cure job Adopt the cement mortar pouring same ,indicia in before the root segment sticking the foam rubber or plastic strip , the bottom puts on a cement mortar , concrete a concrete, first 5 cm ~ 10 cm. Sincewater-proof, concrete structure wall thickness is mostly more infertile .Be to ensure that component geometry dimension , Chang adopt the inside and outside bolt to pull the measure meeting attention to, responds to on play receive bolt centre interpose stop water iron plate, to prevent water from forming pilotage passage along bolt leakage.2.2 Assembing reinforoementWater-proof concrete structure has demanding as follows to the reinforced bar1) reinforced bar should adopt twisted steel as far as possible , increases by hold wrap a force composing in reply a water ability2) reinforced bars connect should try one's best to adopt to solder connection , stop using and being needless to bind connection to the full3) when binding a reinforced bar, the iron wire head responds to inner bending.4) strict control reinforced bars protective layer thickness.Minimal thickness of water-proof concrete reinforced bar protective layer is not smaller than 25 mms , the protective layer welcoming water surface especially inadmissibility to disappoint error,. The iron wire and reinforced bar that application buries in advance within mortar piece whileusing mortar heel block as protective layer, are boundsolid .When the cavalry puts up the fixed reinforced bar if adopt a reinforced bar, Ying Jia also solders water iron plate or fixation just goes ahead, to strengthen water-proof effect in theheel block.This project uses new materials nylon to have fixed there is an effect's had guarded against reinforced bar protective layer deviation piece big mass common failings. The concrete stirring and mixing makes and transportsSince the water-proof concrete requires that higher closely knit , reason why stir and mix system also need to have the fairly good homogeneity , should be ready for burning as follows almost for this purpose1) ensures that mixing time , mixing at every time are secondary jump into a expect the general ejection of compact block of wood less than 2 mins.2) should use the apposition agent , the solution queen who should manufacture certain thickness from apposition agent adds the mixer inner, the dried powder or high concentration solution will add an agent extra not to adds the mixer inner directly ,prevent from mixing is uneven but partconcentrates, both lose the apposition agent effect, and affect concrete mass.3) responds to the assured source of life degree having a spot test on the admeasurement concrete at the regular intervals collapsing in the process being under construction ,construction is middleif Yu rains or other cause, respond to the ratio determining whose water ratio, and adjusting the composition being under construction in time when change happened in sandstone moisture content.4) project uses the commodity concrete , has boundary have raised a concrete stirring mass and of all kinds effect apposition agent adulterating falls when amounts , the water ash having controlled a concrete strictly collapsing.5) concretes concrete adopt a pump to have given handicraft , effective avoiding a concrete producing the phenomenon isolating Mi Shui and leaving out thick fluid in the process of transportation.2.4 Matters needing attention in being under construction1) construction school assignment soft and floury is divided .Water-proof concreting should stratify strictly being in progress, and a continuous construction iscompletedThe front and back and high and low connect between the tier should subjugate within the cement initial settingtime,For this purpose ,with handling a worker dividing into several, at the same time each other, school assignment group faces or it is all right for each other, carry on the back . 2)Achieve strictly fixed point determines the amounts of the components of a substance material down According to the vehicle capacities stratifying concrete altitude and the means of transport, the quantify carrying out fixed point strictly is able to go down one important ring expecting that this is to improve water-proof concreting mass.3) insist that you go down material opening the door or use string to expect that under barrel (chute)Be to prevent a cement paste from parting from aggregate for , to expect that liberty should not exceed 1.5 ms now and then highly under water-proof concrete。

在1782年,英国人John Smeaton为了把他的非军事工程工作区别于当时占优势地位的军事工程师的工作而采用的名词。
自从那时起,土木工程学被用于提及从事公共设施建设的工程师,尽管其包含的领域更为广阔。
Scope. Because it is so broad, civil engineering is subdivided into a number of technical specialties. Depending on the type of project, the skills of many kin ds of civil engineer specialists may be needed. When a project begins, the site is surveyed and mapped by civil engineers who locate utility placement—wat er, sewer, and power lines. Geotechnical specialists perform soil experiments t o determine if the earth can bear the weight of the project. Environmental spe cialists study the project’s impact on the local area: the potential for air and gr oundwater pollution, the project’s impact on local animal and plant life, and h ow the project can be designed to meet government requirements aimed at pr otecting the environment. Transportation specialists determine what kind of facilities are needed to ease the burden on local roads and other transportation networks that will result from the completed project. Meanwhile, structural specialists use preliminary data to make detailed designs, plans, and specific ations for the project. Supervising and coordinating the work of these civil eng ineer specialists, from beginning to end of the project, are the construction m anagement specialists. Based on information supplies by the other specialist s, construction management civil engineers estimate quantities and costs of m aterials and labor, schedule all work, order materials and equipment for the jo b, hire contractors and subcontractors, and perform other supervisory work to ensure the project is completed on time and as specified.领域。
因为包含范围太广,土木工程学又被细分为大量的技术专业。
不同类型的工程需要多种不同土木工程专业技术。
一个项目开始的时候,土木工程师要对场地进行测绘,定位有用的布置,如地下水水位,下水道,和电力线。
岩土工程专家则进行土力学试验以确定土壤能否承受工程荷载。
环境工程专家研究工程对当地的影响,包括对空气和地下水的可能污染,对当地动植物生活的影响,以及如何让工程设计满足政府针对环境保护的需要。
交通工程专家确定必需的不同种类设施以减轻由整个工程造成的对当地公路和其他交通网络的负担。
同时,结构工程专家利用初步数据对工程作详细规划,设计和说明。
从项目开始到结束,对这些土木工程专家的工作进行监督和调配的则是施工管理专家。
根据其他专家所提供的信息,施工管理专家计算材料和人工的数量和花费,所有工作的进度表,订购工作所需要的材料和设备,雇佣承包商和分包商,还要做些额外的监督工作以确保工程能按时按质完成。
Throughout any given project, civil engineers make extensive use of people a nd goods. They specialize in designing and maintaining all types of transportat ion facilities, highways and streets, mass transit systems, railroads and airfiel ds, ports and harbors. Transportation engineers apply technological knowledg e as well as consideration of the economic, political, and social factors in desig ning each project.贯穿任何给定项目,土木工程师都需要大量使用计算机。
计算机用于设计工程中使用的多数元件(即计算机辅助设计,或者CAD)并对其进行管理。
计算机成为了现代土木工程师的必备品,因为它使得工程师能有效地掌控所需的大量数据从而确定建造一项工程的最佳方法。
Structural engineering. In this speciality, civil engineers plan and aesign structures o f all types, including bridges, dams, power plants, supports for equipment, special st ructures for offshore Projects, the United States space program, transmission towers, giant astronomical and radio telescopes, and many other kinds of projects. Using c omputcrs+ structural engineers determine thc forces a structure must resist : its ow n weight, wind nnd hurricane forces, temperature changes that expand or contract construction materials, anel earthquakes. They also determine the combination of ap propriate materials : steel, concrete, plastic, stone, asphalt, brick, aluminum, or othe r construction materials.结构工程学。
