Piles, Reinforced Concreteand Reinforced Concrete StructuresPilesPiles are structural members of timber, concrete, and/or steel, used to transmit surface loads to lower levels in the soil mass. This may be by vertical distribution of the load along the pile shaft or a direct application of load to the lower stratum through the pile point. A vertical distribution of the load is made using a friction pile and a direct load application is made by a point, or end-bearing pile. This distinction of piles is purely one of convenience since all piles function as a combination of side resistance and point bearing except when the pile penetrates an extremely soft soil to a solid base.Piles are commonly used: (1) To carry the superstructure loads into or through a soil stratum. Both vertical and lateral loads may be involved. (2) To resist uplift, or overturning, forces as for basement mats below the water table or to support tower legs subjected to overturning. (3) To compact loose, cohesionless deposits through a combination of pile volume displacement and driving vibrations. These piles may be later pulled. (4) To control settlements when spread footings or a mat is on a marginal soil or is underlain by a highly compressible stratum. (5) To stiffen the soil beneath machine foundations to control both amplitudes of vibration and the natural frequency of the system. (6) As an additional safety factor beneath bridge abutments and/or piers, particularly if scour is a potential problem. (7) In offshore construction to transmit loads above the water surface through the water and into the underlying soil. This is a case of partially embedded piling subjected to vertical( and buckling) as well as lateral loads.Piles are sometimes used to control earth movements (as landslides). The reader should note that power poles and many outdoor sign poles may be considered as partially embedded piles subject to lateral loads. Vertical loads may not be significant, although buckling may require investigation for very tall members.A pile foundation is more expensive than spread footings and likely to be more expensive than a mat. In any case great care should be exercised in determing the soil properties at the site for the depth of possible interest so that it can be accurately determined that a pile foundation is needed and, if so, that neither an excessive number nor lengths are specified. A cost analysis should be made to determine whether a mat or piles, in particular the type (steel, concrete, etc.), are more economical. In those cases where piles are used to control the settlement at marginal soil sites, care should be taken to utilize both the existing ground and the piles in parallel so that a minimum number are required.Piles are inserted into the soil via a number of methods: (1) Driving with a steady succession of blows on the top of the pile using a pile hammer. This produces both considerable noise and vibrations which may be disallowed by local codes or environmental agencies and, of course, may damage adjacent property. (2) Driving using a vibratory device attached to the top of the pile. This is usually a relatively quiet method and driving vibrations may not be excessive. The method is more applicable in deposits with little cohesion. (3) Jacking the pile. This is more applicable for short stiff members. (4) Drilling a hole and either inserting a pileinto it or, more common, filling the cavity with concrete which produces a pile upon hardening. Reinforced ConcretePlain concrete is formed a hardened mixture of cement, water, fine aggregate, coarse aggregate (crushed stone or gravel), air, and often other admixtures. The plastic mix is placed and consolidated in the formwork, then cured to facilitate the acceleration of the chemical hydration reaction of the cement/water mix, resulting in hardened concrete. The finished product has high compressive strength, and low resistance to tension, such that its tensile strength is approximately one tenth of its compressive strength. Consequently, tensile and shear reinforcement in the tensile regions of sections has to be provided to compensate for the weak tension regions in the reinforced concrete element.It is this deviation in the composition of a reinforced concrete section from the homogeneity of standard wood or steel sections that requires a modified approach to the basic principles of structural design. The two components of the heterogeneous reinforced concrete section are to be so arranged and proportioned that optimal use is made of the materials involved. This is possible because concrete can easily be given any desired shape by placing and compacting the wet mixture of the constituent ingredients into suitable forms in which the plastic mass hardens. If the various ingredients are properly proportioned,the finished product becomes strong, durable, and ,in combination with the reinforcing bars, adaptable for use as main members fo any structural system.The techniques necessary for placing concrete depend on the type of member to be cast: that is, whether it is a column, a beam, a wall, a slab, a foundation, a mass concrete dam, or an extention of previously placed and hardened concrete. For beams, columns, and walls, the forms should be well oiled after cleaning them, and the reinforcement should be cleared of rust and other harmful materials. In foundations, the earth should be compacted and thoroughly moistened to about 6in.in depth to avoid absorption of the moisture present in the wet concrete. Concrete should always be placed in horizontal layers which are compacted by means of high frequency power –driven vibrators of either the immersion or external type, as the case requires, unless it is placed by pumping. It must be kept in mind, however, that over vibration can be harmful since it could cause segregation of the aggregate and bleeding of the concrete.Hydration of the cement takes place in the presence of moisture at temperatures above 50℉.It is necessary to maintain such a condition in order that the chemical hydration reaction can take place. If drying is too rapid, surface cracking takes place. This would result in reduction of concrete strength due to cracking as well as the failure to attain full chemical hydration.It is clear that a large number of parameters have to be dealt with in proportioning a reinforced concrete element, such as geometrical width, depth, area of reinforcement, steel strain, concrete strain, steel stress, and so on. Consequently, trial and adjustment is necessary in the choice of concrete sections, with assumptions based on conditions at site, availability of the constituent materials, particular demands of the owners, architectural and headroom requirements, the applicable codes, and environmental conditions. Such an array of parameters has to be considered because of the fact that reinforced concrete is often a site-constructed composite, in contrast to the standard mill-fabricated beam and column sections in steel structures.Reinforced Concrete StructuresReinforced concrete systems are composed of a variety of concrete structural elements that, when synthesized, produce a total system. The components can be broadly classified into: floor slabs, beams, columns, walls, and foundations.Floor Slabs Floor slabs are the main horizontal elements that transmit the moving live loads as well as the stationary dead loads to the vertical framing supports of a structure. They can be proportioned such that they act in one direction (one-way slabs) or proportioned so that they act in two perpendicular direction (two-way slabs).Beams Beams are the structural elements that transmit the loads from floor slabs to vertical supporting columns. They are normally cast monolithically with the slabs and are structurally reinforced on one face, the lower tension side, or both the top and bottom faces. As they are cast monolithically with the slab, they form a T-beam section for interior beams or an L beam at the building exterior, as seen in Fig.2.Columns The vertical elements support the structural floor system. They are compression members subjected in most cases to both bending and axial load, and are of major importance in the safety considerations of any structure. If a structural system is also composed of horizontal compression members, such members would be considered as beam-columns.Walls Walls are the vertical enclosures for building frames. They are not usually or necessarily made of concrete but of any material that aesthetically fulfills the form and functional needs of the structural system. Additionally, structural concrete walls are often necessary as foundation walls, stairwell walls, and shear walls that resist horizontal wind loads and earthquake-induced loads.Foundations Foundations are the structural concrete elements that transmit the weight of the superstructure to the supporting soil. They could be in many forms, the simplest being the isolated footing shown in Fig.2. It can be viewed as an inverted slab transmitting a distributed load from the soil to the column.桩基础、钢筋混凝土和钢筋混凝土结构桩基础桩是由木材、混凝土和(或)钢制成的结构构件,被用来把荷载传递到土体的较深处。

INTRODUCTIONThe investigation and re-use evaluation of many Irish boulder clay soils presents difficulties for both the geotechnical engineer and the road design engineer. These glacial till or boulder clay soils are mainly of low plasticity and have particle sizes ranging from clay to boulders. Most of our boulder clay soils contain varying proportions of sand, gravel,cobbles and boulders in a clay or silt matrix. The amount of fines governs their behaviour and the silt content makes it very weather susceptible. Moisture contents can be highly variable ranging from as low as 7% for the hard grey black Dublin boulder clay up to 20-25% for Midland, South-West and North-West light grey boulder clay deposits. The ability of boulder clay soils to take-in free water is well established and poor planning of earthworks often amplifies this.The fine soil constituents are generally sensitive to small increases in moisture content which often lead to loss in strength and render the soils unsuitable for re-use as engineering fill. Many of our boulder clay soils (especially those with intermediate type silts and fine sand matrix) have been rejected at the selection stage, but good planning shows that they can in fact fulfil specification requirements in terms of compaction and strength.The selection process should aim to maximise the use of locally available soils and with careful evaluation it is possible to use or incorporate ‘poor or marginal soils’ within fill areas and embankments. Fill material needs to be placed at a moisture content such that it is neither too wet to be stable and trafficable or too dry to be properly compacted.High moisture content / low strength boulder clay soils can be suitable for use as fill in low height embankments (i.e. 2 to 2.5m) but not suitable for trafficking by earthwork plant without using a geotextile separator and granular fill capping layer. Hence, it is vital that the earthworks contractor fully understands the handling properties of the soils, as for many projects this is effectively governed by the trafficability of earthmoving equipment.2. TRADITIONAL GROUND INVESTIGATION METHODSFor road projects, a principal aim of the ground investigation is to classify the suitability of the soils in accordance with Table 6.1 from Series 600 of the NRA Specification for Road Works (SRW), March 2000. The majority of current ground investigations for road works includes a combination of the following to give the required geotechnical data:▪Trial pits▪Cable percussion boreholes▪Dynamic probing▪Rotary core drilling▪In-situ testing (SPT, variable head permeability tests, geophysical etc.)▪Laboratory testingThe importance of ‘phasing’ the fieldwork operations cannot be overstressed, particularly when assessing soil suitability from deep cut areas. Cable percussion boreholes are normally sunk to a desired depth or ‘refusal’ with disturbed and un disturbed samples recovered at 1.00m intervals or change of strata.In many instances, cable percussion boring is unable to penetrate through very stiff, hard boulder clay soils due to cobble, boulder obstructions. Sample disturbance in boreholes should be prevented and loss of fines is common, invariably this leads to inaccurate classification. Trial pits are considered more appropriate for recovering appropriate size samples and for observing the proportion of clasts to matrix and sizes of cobbles, boulders. Detailed and accurate field descriptions are therefore vital for cut areas and trial pits provide an opportunity toexamine the soils on a larger scale than boreholes. Trial pits also provide an insight on trench stability and to observe water ingress and its effects.A suitably experienced geotechnical engineer or engineering geologist should supervise the trial pitting works and recovery of samples. The characteristics of the soils during trial pit excavation should be closely observed as this provides information on soil sensitivity, especially if water from granular zones migrates into the fine matrix material. Very often, the condition of soil on the sides of an excavation provides a more accurate assessment of its in-situ condition.3. ENGINEERING PERFORMANCE TESTING OF SOILSLaboratory testing is very much dictated by the proposed end-use for the soils. The engineering parameters set out in Table 6.1 pf the NRA SRW include a combination of the following:▪Moisture content▪Particle size grading▪Plastic Limit▪CBR▪Compaction (relating to optimum MC)▪Remoulded undrained shear strengthA number of key factors should be borne in mind when scheduling laboratory testing:▪Compaction / CBR / MCV tests are carried out on < 20mm size material.▪Moisture content values should relate to < 20mm size material to provide a valid comparison.▪Pore pressures are not taken into account during compaction and may vary considerably between laboratory and field.▪Preparation methods for soil testing must be clearly stipulated and agreed with the designated laboratory.Great care must be taken when determining moisture content of boulder clay soils. Ideally, the moisture content should be related to the particle size and have a corresponding grading analysis for direct comparison, although this is not always practical.In the majority of cases, the MCV when used with compaction data is considered to offer the best method of establishing (and checking) the suitability characteristics of a boulder clay soil. MCV testing during trial pitting is strongly recommended as it provides a rapid assessment of the soil suitability directly after excavation. MCV calibration can then be carried out in the laboratory at various moisture content increments. Sample disturbance can occur during transportation to the laboratory and this can have a significant impact on the resultant MCV’s.IGSL has found large discrepancies when performing MCV’s in the field on low plasticity boulder clays with those carried out later in the laboratory (2 to 7 days). Many of the aforementioned low plasticity boulder clay soils exhibit time dependant behaviour with significantly different MCV’s recorded at a later date – increased values can be due to the drainage of the material following sampling, transportation and storage while dilatancy and migration of water from granular lenses can lead to deterioration and lower values.This type of information is important to both the designer and earthworks contractor as it provides an opportunity to understand the properties of the soils when tested as outlined above. It can also illustrate the advantages of pre-draining in some instances. With mixed soils, face excavation may be necessary to accelerate drainage works.CBR testing of boulder clay soils also needs careful consideration, mainly with the preparation method employed. Design engineers need to be aware of this, as it can have an order of magnitude difference in results. Static compaction of boulder clay soils is advised as compaction with the 2.5 or 4.5kg rammer often leads to high excess pore pressures being generated –hence very low CBR values can result. Also, curing of compacted boulder clay samples is important as this allows excess pore water pressures to dissipate.4. ENGINEERING CLASSIFICATION OF SOILSIn accordance with the NRA SRW, general cohesive fill is categorised in Table 6.1 as follows:▪2A Wet cohesive▪2B Dry cohesive▪2C Stony cohesive▪2D Silty cohesiveThe material properties required for acceptability are given and the design engineer then determines the upper and lower bound limits on the basis of the laboratory classification and engineering performance tests. Irish boulder clay soils are predominantly Class 2C.Clause 612 of the SRW sets out compaction methods. Two procedures are available:▪Method Compaction▪End-Product CompactionEnd product compaction is considered more practical, especially when good compaction control data becomes available during the early stages of an earthworks contract. A minimum Target Dry Density (TDD) is considered very useful for the contractor to work with as a means ofchecking compaction quality. Once the material has been approved and meets the acceptability limits, then in-situ density can be measured, preferably by nuclear gauge or sand replacement tests where the stone content is low.As placing and compaction of the fill progresses, the in-situ TDD can be checked and non-conforming areas quickly recognised and corrective action taken. This process requires the design engineer to review the field densities with the laboratory compaction plots and evaluate actual with ‘theoretical densities’.5. SUPPLEMENTARY GROUND INVESTIGATION METHODS FOR EARTHWORKSThe more traditional methods and procedures have been outlined in Section 2. The following are examples of methods which are believed to enhance ground investigation works for road projects:▪Phasing the ground investigation works, particularly the laboratory testing▪Excavation & sampling in deep trial pits▪Large diameter high quality rotary core drilling using air-mist or polymer gel techniques译文:土方工程的地基勘察与施工1、引言许多爱尔兰含砾粘土的勘察与再利用评价使岩土工程师与道路工程师感到为难。

建筑工程中桩基检测技术问题分析中英文对照Analysis and testing technology of pile foundation construction in Chinese and English.桩基是影响工程质量的基础因素,并且桩基这一影响因素还是隐性的影响因素。

作为地面建筑的一种支撑,好的桩基会让结构的基础更加的稳定,而质量劣质的桩基,会对结构的安全造成恶劣的影响。

因此,对于基础施工,桩基的检测是一个不可或缺的技术环节。

并且随着现代工程的进步,对于质量和安全系数的要求越来越高,对于特殊的结构群体,诸如高层建筑以及铁路建筑的建设中桩基技术不断的发展,因而建设工程单位所面临的要求也越来越高,越来越严格,这个时候桩基的检测技术就可以发挥出应有的作用报这个桩基质量。

Pile foundation is the basic factors influencing the engineering quality, influencing factors and the influencing factors of pile or recessive. As a supporting ground buildings, the pile will make structure more stable, and the quality inferior pile foundation, will cause bad influence on the safety of structure. Therefore, for the foundation construction, pile foundation detection is an indispensable link. And with the development of modern engineering progress, growing demand for quality and safety factor, the structure of special groups, such as the development of high-rise building pile foundation construction and railway construction in technology, so the construction units are facing the increasingly high demand, more and more strict, the pile foundation detection technology can play a role on the quality of pile foundation should be.1 桩基的检测技术分析Analysis and testing technology 1 pile foundation1.1 成孔的质量检测Quality inspection of 1.1 into the hole在对成孔的质量进行检测时,主要的检测部位有桩孔的位置检测、孔径以及孔深的监测。

底沉渣的厚度监测和垂直度的监测等等。

成孔的质量直接归决定桩基的柱体的成桩质量,过时桩孔在孔径上的直径偏小,那么整个桩的承载力就会有所下降;而若是孔径扩大,那么整个桩在上部的侧阻力优惠随之增大,下部就不能发挥侧阻力应有的作用;另外,桩孔的垂直程度也会对承载力造成影响,偏斜的基桩会阻碍桩基的作用发挥;最后若是底部的沉渣太多就会令桩体的有效长度减少,那么也会对桩体的质量造成影响。

因此,这些问题的检测工作就尤为重要了。

/ /On the test of the quality of pore, position detection, detection part mainly have the pile hole diameter and hole depth monitoring. Thickness monitoring and verticality of bottom sediment monitoring etc.. The quality of the pile hole quality directly to the cylinder pile decision, outdated pile hole in aperture of the diameter is small, so the bearing capacity of the pile will decrease; and if the size, then the whole pile side resistance concessions in the upper part of the increase, the lower part can not play the role of side resistance due; in addition, the vertical extent of pile hole can also impact on the bearing capacity of the pile deflection, play will hinder the pile foundation; finally, if the effective length of the bottom sediment too much will make the pile decreases, it will affect the quality of pile body. Therefore, detection of these problems is particularly important.1.2 承载力检测分析1.2 bearing capacity analysis1.2.1 静荷载试验法。

这种方式在对于桩基的检测上主要是检测承载力,桩基在水平上的承载力以及在竖直方向上的承载力是桩基质量的衡量标准,同时也是对建筑的影响最大的因素,这里就需要用到静荷载实验的方式。

一般的工程检测中大多都是对竖直方向上的承载力较为重视。

这种检测方式的有点就是利用了和桩基实际会承受的力度去模拟实验对其受理的条件进行试验。

这种方式一般都应用在对于工程试桩的检测上,在不破坏桩基的基础上对其进行检测。

并且精度很高,误差低于10%。

1.2.1 static load test method. In this way for pile foundation detection is detection of bearing capacity, bearing capacity of pile foundation in the level and capacity in the vertical direction is a standard measure of quality of pile foundation, but also the impact on building the biggest factor, here we need to use the static load experiment method. The general engineering detection mostly has attached more importance to the bearing capacity of the vertical direction. This detection method is a little use and actual pile foundation will bear the efforts to simulate the experimental test of the admissibility condition. This is generally used in the detection for engineering test pile, the pile foundation detection without destroying the. And the precision is very high, the error is less than 10%.1.2.2 高应变动法。

这种方式是通过对桩体在接近极限承载力的时候的状态分析,这就需要利用到重锤这一机械方式的瞬间冲击力,令桩体周围的土产生变形。

在结合其实际测量力度以及速度时,通过数据的曲线分析,结合应力波的理论以及桩体的有关参数,对桩体的极限工作能力进行分析。

/ /1.2.2 high strain method. This way is through the analysis of the status of pile body when approaching the limit bearing capacity, it will need to use the weight that a mechanical means of instantaneous impact force, the pile surrounding soil deformation. In combination with the actual measurement of strength and speed, through the analysis of data curve, combined with the relevant parameters of the stress wave theory and the analysis of pile, ultimate working capacity of piles.1.3 完整性的检测分析Detection and analysis of 1.3 integrity1.3.1 低应变动的测法。

这种测法就是通过波动理论以及机械阻抗理论进行试验分析,在桩顶是假一个较低振幅的激振能量。

通过这种能量对土体的周围进行环境改变,引起桩身以及土体在桩身周围的微幅振动。

同时使用仪表对加速度以及振动的速度进行记录以及分析,并通过分析达到控制和检验桩基的目的,对桩基的质量进行保障,对桩身的完整性进行保证以及达到对桩基承载力的预测目的。

1.3.1 low strain dynamic testing. This method is tested through the analysis of the wave theory and the mechanical impedance theory, on top of the pile is a low amplitude vibration energy. Environmental change through the energy of soil around the pile and the soil, causing the micro-amplitude vibration around the pile shaft. At the same time, the use of instrument for recording and analysis of vibration acceleration and velocity, and achieve the control and inspection of pile foundation through the analysis of the objective, for the guarantee of the quality of the pile foundation, guarantee and the purpose of prediction of bearing capacity of pile integrity of pile body.1.3.2 声波透射检测法。
