建筑电气

电气工程设计包括两个主要的设计方面。主要是一部分的电能的转换及分配和电力的供配、照明系统、防雷接地系统。一般来说,建筑主要的变化包括:高压和低压配电系统、变压器、备用电源系统。电力系统包括配电和控制,室内和室外照明系统包括所有类型的照明,防雷系统包括入侵波防护、闪电传感器、接地、等电位连接和局部等电位连接等。辅助等电位连接等。在短短的20年里,系统在技术和产品的面貌发生了翻天覆地的变化。许多的设计理念也发生了巨大的变化。开关设备如高压系统的第一个断路器油断路器,后来油断路器的逐步发展,不仅规模大,但是一般都包含油物质。由于开关设备尺寸较大,我们还必须建立独立的设备房间,占据了大量的建筑面积。现在真空断路器和六氟化硫断路器,不仅体积小,而且短路容量大,外壳尺寸远小于原来的橱柜,并且断路器没有任何油,防火性能大大提高。而且断路器和其他低压设备在一个房间里,这样即节省空间又方便管理。过去大容量的低压断路器,短路电流容量逐渐变大,规模也逐渐变小,而且更加稳定,使系统运行更加安全可靠,为设计带来了方便。向着智能化低压断路器方向发展,断路器各种参数可以通过总线工业控制,信号直接传输到计算机。

干式变压器的出现,对建筑电气设计带来了极大的方便,因为没有变压器油泄漏和火灾的可能性,以便它可以很容易地安装在建筑本身,甚至直接到负荷中心。它还消除变压器对油的需求限制,构建大容量设备时可以使用干式变压器。在实际工程设计中曾应用四个台湾2500kVA干式变压器。

在使用紧急发电机方面,从性能和尺寸的角度来看,比过去进步很多。除了使用柴油发电机;应急照明使用EPS备用电源;中断供电在一个毫秒以内的设备,可以使用UPS。

电力设备的控制从单一元件的控制到控制继电器控制变化。除了更好的性能的各种组件的规模较小,也降低控制箱的规模。由于数字技术更多的运用于控制能达到最佳的控制状态来控制设备。进一步提高了节能的效果。

照明系统从过去单一光源、灯具和低效率的状态向更广泛的前景发展。建筑中使用的光源可供选择的品种数量很多。光的发光效率和色调在向着高效的方向发展,灯具不断地改进其效率和不同形式的灯具运用于不同场合。例如,普通的荧光灯镇流器由普通的镇流器向节能型镇流器方向发展。还对谐波组件的大小进行精简,生产低谐波电子镇流器。许多措施如配件和灯具的使用,可以满足设计要求,同时能实现不同的体系结构、照明要求的各种场所。无论照明和室内装饰照明还

是道路照明和户外庭院建筑的光照明,所有的都展示了照明技术的发展和建筑照明的好处与便利。

另一个设计使用于电气设备和其他设备,如双电源开关的互投。与传统的专业生产产品相比,除了传统的功率切换外,双电源还能满足每个其他电子设备的需要,极大地提高供电的可靠性和连续性。

电力电缆和电线是被广泛使用的产品。过去的电线电缆,种类稀少。现在引入各种电缆,从普通阻燃PVC电缆到耐火、少烟无卤、防电磁干扰环境的电缆等。导线材料从普通的矿物绝缘绝缘材料到总线绝缘,高效绝缘等分支机构。电力建设中这些技术是安全、可靠、方便的,提供了一个有效的环境保护。

针对特殊需求分布、建设的一些新设备得到了广泛的应用。例如大型医院手术室医疗机构漏电保护、漏电监测系统等。

技术的发展强大在很多地方都有显现如实际工程和技术人员,以及我们自己的经验。如此巨大的发展为中国的电力建设和电力建设安全使用奠定了良好的基础也创造了条件。

随着建筑智能化技术的深入应用,一些设备、系统控制和控制系统已逐渐成为一个专业性的监控,并具有开放建筑设备监控系统通信协议、互联网和通信系统。建筑物内如自动功率控制系统,采用现场总线技术的数据采集和处理,集中控制变量分配系统实现远程监控和远程控制以及远程无人变电站的实现。连续收集和分析系统能提前给出建议或警告,以方便系统的安全运行。自动功率控制系统利用计算机技术、信息技术、控制技术、传感器技术、通信网络技术、电力电子技术等综合技术,它基本上可以取代传统的二次回路而且接线简单、性能可靠、易于维护。与此同时,根据建筑的能耗进行的第二次重大节能照明控制系统也会逐步实现。专业照明控制系统已经广泛应用于许多建筑物。照明控制由一个实时传感器控制定时控制。此外,现场控制、远程控制和控制多种灵活的控制现场,达到最大的能量利用,同时实现功能和人性化的舒适的照明系统。

各种建筑标准也相应出台,如1980年代末《标准建筑设计防火规范》GBJ16-87;1990年代《民用建筑照明设计标准》GBJ133-90;《民用建筑电气设计规范》JGJ/ T16 - 92;《工业企业照明设计标准》GB50034 - 92;《高层民用建筑设计防火规范》GB50045 - 95;《供配电系统设计规范》GB50052 - 95;《l0kV及以下变电所设计规范》GB50053 - 94;《低压配电设计规范》GB50054 - 95;《通用用电设备设计规范》GB50055 - 93;《建筑物防雷设计规范》GB50057-94等等。紧随后

的是建筑电气设计基础建设电气设计的标准化。

智能建筑技术只是一种手段,配备智能功能、强调效率、能耗低、更干净,真正实现以人为本。在实现节能的前提下,提高建筑的功能、环境保护和可持续发展的目标。构建可持续发展的实现从战略的角度来看,注重环境保护,保持生态系统稳定。可持续发展是一个永恒的主题,经过多年的实践,在一个理性和务实的态度下,以实际需要和实际应用为标准,不是盲目地追随片面而是追求全面、先进的智能系统,在技术上做到领先。设计需做了合理的投资,使用不同的功能。根据投资和管理需求的具体情况来确定先进的、可靠的、经济合理的和最优的方案,这个概念现在已经成为智能建筑行业的共识。建筑智能技术使所有的学院和大学的建设开辟了这一技术相应的专业课程和促进了相关专业学生的发展。

智能建筑技术包括:建筑设备自动控制系统、安全系统、停车场管理系统、火灾自动报警和消防系统、通信和计算机网络系统、综合布线系统、广播系统、有线电视系统、视频会议系统等,超过10个子系统的集成。是我国第一个独立于国内建筑智能技术系统集成子系统的开发。

1、20世纪的建筑设备监控系统的发展由1980年代的集中监控开始,由于可靠性差、速度慢,1990年代后已经很少使用,并取代了分布式控制。在1990年代末,随着计算机技术、控制技术、网络和通信技术开发和集成,监控施工设备技术发展迅速。

2、安全技术和安全措施也逐步发展,包括中央监控、入侵警报、访问控制(门)、巡逻削减等更多的周边防御和其他子系统。安全系统从最初的子系统相互独立的到各子系统之间相互联系。大大增加了安全性、可靠性和实时为人们的工作、学习和生活安全保障。闭路电视监控系统从模拟到数字的方向发展,整个安全系统的规模也在运动数字系统、集成的方向发展。

3、运用通信网络技术的智能建筑通信网络,包括计算机网络、双向有线电视传输网络和电话通讯网络。前两个智能网络作为一个宽带主干网络把几乎所有的信息技术和信息资源管理的几乎所有的用户连接到一起。在1990年代中期之前,有一个为所有类型的网络和用户的市场。但在1990年代末,由于以太网连接的灵活性和优越的性能、易于维护和使用等优点,ICT网络逐渐在列表中。以太网传输速率,从最初的10Mbps,100Mbps 到1 Gbps,10Gbps甚至更高的利率。智能建筑电话网络(ISDN,SL)目前用于语音通信、数据和图像的窄带宽数据通信,它让人们通过通信网络、电视、电话会议等功能实现相互交流。智能访问技术的关键是与

外界建立联系,它使世界变得越来越小。人们的工作、生活发生了剧大的变化。智能建筑访问网络或互联网,越来越多的高带宽需求的接收,满足日益增长的用户需求数据通信。在有线电视网络的发展同时,无线网络由于其灵活性,也进入了一个快速发展阶段。从2003年的基于最初的路线的轮询策略的研究到现在超过100兆赫。移动互联网正为人们提供很大的方便,并在许多领域发展潜力巨大,网络正在成为趋势。

4、综合布线技术PDS是智能建筑数据、语音和多媒体的通信平台。综合布线技术进入中国市场以来,因其优异的性能,并且对于智能建筑的国内市场来说是一个新概念、新技术,在建筑业立即引起了巨大的反响。该技术已广泛应用于所有类型的智能建筑。为了满足网络传输带宽和新产品的开发速度,PDS引入3线、5线到6线,甚至提高标准到七线系统的产品,以满足千兆网络的需求。提高网络的传输速率,以适应已经投入10G网络市场的发展。新的多模和单模光纤传输媒介作为一个很好的材料将被广泛使用。从铜线、光纤电缆、技术和产品的不断更新,PDS充分反映了智能建筑的快速发展,新技术的应用和广阔的发展前景。

5、智能建筑系统集成技术一般连接各个子网络。每个子系统的操作预计将完成他们的工作,但尚未达到共享信息资源。为了实现有效的管理,各个子系统之间的信息资源共享、系统集成。在系统集成过程中,选择平台集成、网络结构、集成子系统的范围是不同的、集成模型也是不同的。随着计算机技术、网络技术、控制技术、显示技术的发展,建筑设备监控系统和其他系统通过计算机网络连接。完成基于建筑设备监控系统的系统集成模式。平等的在各自的系统集成,建立一个网络管理系统集成。作为一个子系统可以降低现场控制网络集成。实时数据子系统、开放、行业标准接口,转换成统一的格式存储在数据库或服务器系统集成。综合网络管理系统实现统一管理子系统程序、监控和信息交换系统集成, 系统集成实现协议的各个子系统之间的联系有关控制和信息共享。提高管理效率,增强处理突发事件的能力和节约能源的目的、节省人力。这是建筑设备管理系统(BMS)。系统集成不是我们的目的,而是为了增强建筑的功能和技术手段,提高管理效率,整合内容不是更好,但根据使用和管理的需要,以及成熟的技术,该系统是可靠和合理的投资。有效管理的前提是集成的需求。

(6)智能住宅区

1990年代国际电子智能住宅提出的理念。智能建筑技术逐渐蔓延到居民区,在最初几个经济较发达的沿海城市已经成功。智能技术开始建设居住小区的住宅

和公共建筑。智能建筑智能技术迅速扩展,已成为智能建筑发展的一个重要市场。公共建筑和住宅智能化,这是市场的需求,也是实际的发展需求。智能设计研究所将中国住宅将放在一个重要位置,为住宅提供一个智能平台。住宅的智能设计是先进的和具有挑战性的领域。住宅小区智能化技术的发展可以分为以下方面:系统设计强调以人为本的设计理念,应该迎合居民所有级别的方便、安全、舒适和处理功能的要求,处理好先进和实用之间的关系和合理的投资。安全系统从一个单独的安全子系统为家庭和社区结合防御到国防安全的技术体系。从单个运营商宽带访问信息、通信模式选项、xD-SL宽带接入网络、一个双向有线电视网络,形成地区计算机网络发展。当地居民可以享受信息和通讯服务从一个宽带互联网服务地区接收更多的局域网的延伸增值服务。机电设备的自动监控、电子水位远程复制、音频和视频系统、信息技术和其他物业管理系统,区域居民的生活环境和生活质量大大提高。智能家居的应用,当地居民实际生活经验的信息时代,各种各样的便利和各种各样的家庭办公室,网络概念已成为一个现实的生活。

Many of the design concept has also undergone tremendous changes. Swichgear such as high pressure system, the first circuit breaker to the oil circuit breakers. After the progressive development of the oil circuit breakers, is not only large in size, but did not fire. Swichgear are larger allocation, we must also set up independently in heir own rooms, occupied a lot of the construction area. Now a vacuum circuit breaker andSF6 circuit breakers, is not only small size but also high-capacity short-circuit. enclosure size is a lot smaller than the original cabinets, circuit breakers without any oil, fire performance greatly improved. with a total of home and other low-voltage equipment in a room, saving both space and convenience of management. The large volume of low-voltage circuit breaker from the past, the development of small to large short-circuit current capacity, the ability to continue to score small in size, stable, which makes the system more secure and reliable, and designed to bring the convenience. Intelligent direction toward another recent low voltage circuit breaker, breaker various parameters can be controlled through the bus industry, Signals transmitted to the computer directly.

The emergence of dry-type transformers, electrical design for the building posed a great convenience, Because there is no possibility of transformer oil spills and fires, so that it can be easily installed in the building itself, even go directly to the load center. It also eliminated restrictions on capacity building in the transformer oil, building greater capacity for dry-type transformers can be used. In the designs of the project, on the application of four Taiwan2500kV A dry-type transformers.

Used emergency power generators, from the performance and size perspective,there is a lot of progress than in the past. In addition to the use of diesel generators works, as emergency lighting, we use EPS. Allowing a millisecond interruption in the supply of equipment, we can use UPS.

PA VEMENT PROBLEMS CAUSED BY COLLAPSIBLE SUBGRADES By Sandra L. Houston,1 Associate Member, ASCE (Reviewed by the Highway Division) ABSTRACT: Problem subgrade materials consisting of collapsible soils are com- mon in arid environments, which have climatic conditions and depositional and weathering processes favorable to their formation. Included herein is a discussion of predictive techniques that use commonly available laboratory equipment and testing methods for obtaining reliable estimates of the volume change for these problem soils. A method for predicting relevant stresses and corresponding collapse strains for typical pavement subgrades is presented. Relatively simple methods of evaluating potential volume change, based on results of familiar laboratory tests, are used. INTRODUCTION When a soil is given free access to water, it may decrease in volume, increase in volume, or do nothing. A soil that increases in volume is called a swelling or expansive soil, and a soil that decreases in volume is called a collapsible soil. The amount of volume change that occurs depends on the soil type and structure, the initial soil density, the imposed stress state, and the degree and extent of wetting. Subgrade materials comprised of soils that change volume upon wetting have caused distress to highways since the be- ginning of the professional practice and have cost many millions of dollars in roadway repairs. The prediction of the volume changes that may occur in the field is the first step in making an economic decision for dealing with these problem subgrade materials. Each project will have different design considerations, economic con- straints, and risk factors that will have to be taken into account. However, with a reliable method for making volume change predictions, the best design relative to the subgrade soils becomes a matter of economic comparison, and a much more rational design approach may be made. For example, typical techniques for dealing with expansive clays include: (1) In situ treatments with substances such as lime, cement, or fly-ash; (2) seepage barriers and/ or drainage systems; or (3) a computing of the serviceability loss and a mod- ification of the design to "accept" the anticipated expansion. In order to make the most economical decision, the amount of volume change (especially non- uniform volume change) must be accurately estimated, and the degree of road roughness evaluated from these data. Similarly, alternative design techniques are available for any roadway problem. The emphasis here will be placed on presenting economical and simple methods for: (1) Determining whether the subgrade materials are collapsible; and (2) estimating the amount of volume change that is likely to occur in the 'Asst.

Gee Journal 31.4457-465457?1993 (Dec) by Kluwer Academic Publishers Ecotoufism in the Small Island Caribbean Weave~ David B., Prof. Dl:, UniversiO, of Regina, Luther College, Regina, Saskatchewan $4S OA2, Canada ABSTRACT: Ecotourism-related strategies can serve to enhance the tourism industries of small Caribbean islands, which are presently dominated by a 3S (sea, sand, sun) product. In the first place, the principles of Alternative Tourism can be applied to 3S tourism in order to minimize negative environmental impacts. Secondly, diversionary ecotourism opportunities can be promoted to diversify the tourism product, thus providing a nature-oriented alternative to resort-based tourists. Thirdly, regional ecotourism, catering to ecotourists, can be fostered in mountainous interiors, peripheral islands, undeveloped coastlines, rural agricultural areas and in offshore reefs. A fourth strategy, exemplified by Dominica, entails a comprehensive ecotourism approach for destinations in which 3S tourism is undesired or unsuited. Introdactien The concept of ecotourism has attracted a considerable amount of interest among both academics and non-academics since the term was first introduced in the mid-1980s (see for example Boo t990; Goriup 1991; Lindberg 1991; Nelson, Butler and Wall 1993; Whelan 1991; Ziffer 1989). In a frequently cited definition, Ceballos-Lascurain (1988) characterizes ecotourism as Tourism that involves travelling to relatively undisturbed or uncontaminated natural areas with the specific object of studying, admiring and enjoying the scenery and its wild plants and animals, as well as any existing cultural aspects (both past and present) found in these areas. While this definition is useful in stressing the environmental orientation of ecotourism, it is clear that the term has also come to be associated with a range o f characteristics which collectively define an "alternative tourism" (AT) paradigm (Dernoi 1981; Krippendorf 1987; Singh, Theuns and Go 1989). This paradigm has emerged as an alternative to "conventional mass tourism" (CMT), which has been criticized as an often inappropriate form of tourism, especially for smaller destinations. CMT characteristics, outlined and contrasted in Tab 1 with the AT model, tend to appear during the middle and later stages of a destination's cycle of evolution (Butler 1980; Christaller 1963; Stansfield 1978). With respect to accommodations, attractions, market and economic impact, the argument can be made that ecotourism and AT are merely other names for the early "exploration" stage of the resort cycle, when relatively unspoiled areas are opened up to further tourist incursions by a few pioneer travellers. However, as pointed out by Weaver (1991), what distinguishes this "circumstantial" AT from "deliberate" AT is the lack of regulations and policies which attempt to ensure that the activity is maintained at environmentally, economically and socially sustainable levels. "Deliberate" ecotourism, the subject of this paper, is therefore very" much associated with intentions of identifying and working within the carrying capacities of a particular area, and o f discouraging the emergence of a CM T product where it is deeme d to be undesirable or inappropriate. The recent proliferation of ecotourism case studies, based largely in the underdeveloped world, is not surprising in light of deliberate ecotourism's status as the fastest growing form o f tourism (Whelan 1991).

转型衰退时期的土木工程研究 Sergios Lambropoulosa[1], John-Paris Pantouvakisb, Marina Marinellic 摘要 最近的全球经济和金融危机导致许多国家的经济陷入衰退,特别是在欧盟的周边。这些国家目前面临的民用建筑基础设施的公共投资和私人投资显著收缩,导致在民事特别是在民用建筑方向的失业。因此,在所有国家在经济衰退的专业发展对于土木工程应届毕业生来说是努力和资历的不相称的研究,因为他们很少有机会在实践中积累经验和知识,这些逐渐成为过时的经验和知识。在这种情况下,对于技术性大学在国家经济衰退的计划和实施的土木工程研究大纲的一个实质性的改革势在必行。目的是使毕业生拓宽他们的专业活动的范围,提高他们的就业能力。 在本文中,提出了土木工程研究课程的不断扩大,特别是在发展的光毕业生的潜在的项目,计划和投资组合管理。在这个方向上,一个全面的文献回顾,包括ASCE体为第二十一世纪,IPMA的能力的基础知识,建议在其他:显著增加所提供的模块和项目管理在战略管理中添加新的模块,领导行为,配送管理,组织和环境等;提供足够的专业训练五年的大学的研究;并由专业机构促进应届大学生认证。建议通过改革教学大纲为土木工程研究目前由国家技术提供了例证雅典大学。 1引言 土木工程研究(CES)蓬勃发展,是在第二次世界大战后。土木工程师的出现最初是由重建被摧毁的巨大需求所致,目的是更多和更好的社会追求。但是很快,这种演变一个长期的趋势,因为政府为了努力实现经济发展,采取了全世界的凯恩斯主义的理论,即公共基础设施投资作为动力。首先积极的结果导致公民为了更好的生活条件(住房,旅游等)和增加私人投资基础设施而创造机会。这些现象再国家的发展中尤为为明显。虽然前景并不明朗(例如,世界石油危机在70年代),在80年代领先的国家采用新自由主义经济的方法(如里根经济政策),这是最近的金融危机及金融危机造成的后果(即收缩的基础设施投资,在技术部门的高失业率),消除发展前途无限的误区。 技术教育的大学所认可的大量研究土木工程部。旧学校拓展专业并且新的学校建成,并招收许多学生。由于高的职业声望,薪酬,吸引高质量的学校的学生。在工程量的增加和科学技术的发展,导致到极强的专业性,无论是在研究还是工作当中。结构工程师,液压工程师,交通工程师等,都属于土木工程。试图在不同的国家采用专业性的权利,不同的解决方案,,从一个统一的大学学历和广泛的专业化的一般职业许可证。这个问题在许多其他行业成为关键。国际专业协会的专家和机构所确定的国家性检查机构,经过考试后,他们证明不仅是行业的新来者,而且专家通过时间来确定进展情况。尽管在很多情况下,这些证书虽然没有国家接受,他们赞赏和公认的世界。 在试图改革大学研究(不仅在土木工程)更接近市场需求的过程中,欧盟确定了1999博洛尼亚宣言,它引入了一个二能级系统。第一级度(例如,一个三年的学士)是进入

外文文献翻译 2.5.1译文:看电影的艺术 1930年代中期,沃尔特·迪斯尼才明确以动画电影娱乐观众的思想,动画片本身才成为放映主角(不再是其他剧情片的搭配)。于1937年下半年首映的动画片《白雪公主与七个小矮人》为动画片树立了极高的标准,至今任然指导着动画艺术家们。1940年,这一年作为迪斯尼制片厂的分水岭,诞生了《木偶奇遇记》和《幻想曲>。这些今天成为经典的作品在接下来的二十年中被追随效仿,产生了一系列广受欢迎的动画娱乐作品。包括《小飞象》,《灰姑娘》,《爱丽丝漫游仙境》,《彼得·潘》,《小姐与流浪儿》,他们的故事通常源自广为人知的文学故事。这些影片最不好的地方在于它们似乎越来越面向小观众。 在1966年第四你去死后,他的制片厂继续制作手绘动画影片,但是创作能量衰减,公司转而专注于著作真人是拍电影。然而1989年,对于我们所有孩子来说,动画《小美人鱼》赋予了迪士尼新的生命活力(就像animation这个词本身的定义一样——使有生命活力),从该片开始,出现了一系列令人惊叹不已的音乐动画片。两年后,《美女与野兽》问世,塔尔在制作过程中利用了计算机作为传统手绘技术的辅助手段,这部影片获得了奥斯卡最佳电影奖提名,它是第一部获此殊荣的动画片。更好的还在后面,就想着两部影片一样,后面紧接着出现的众多优秀作品——包括《狮子王》,《阿拉丁》,《花木兰》——延续了迪士尼的经典传统:大胆醒目的视觉效果、精致的剧本,以及我们在所有伟大的电影中,不管是动画还是其他类型中都能找到的普适性主题和出乎意料之处。迪士尼的新版《幻想曲》,又被称为《幻想曲2000》,把原版中的部分片段与新的创作部分糅合在一起。(而且,按照迪士尼管理层的说法,该片是首部在IMAX巨幕影院首映的剧情长片。) 亨利·塞利克执导了蒂姆·波顿出品的两部影片,即《圣诞惊魂夜》和《飞天巨桃历险记》——前者是一部完全原创的定格动画,影片画面有时渗透着无限的恐惧,后者改编自罗纳德·达尔的畅销儿童书,该影片以真人实景拍摄开始。《飞天巨桃历险记》对暴力画面和重大恐惧(比如说,离弃)的表达和处理毫无掩饰,表达的真实感受对成人来说和对儿童一样生动鲜明,而蒂姆·波顿的影片《僵尸新娘》,仅仅从名字上就已经显示出影片内容和该幽默表达的“成人”特

开挖工程支撑体系的发展 1.引言 几乎所有土木工程建设项目(如建筑物,道路,隧道,桥梁,污水处理厂,管道,下水道)都涉及泥土挖掘的一些工程量。往往由于由相邻的结构,特性线,或使用权空间的限制,必须要一个土地固定系统,以允许土壤被挖掘到所需的深度。历史上,许多挖掘支撑系统已经开发出来。其中,现在比较常见的几种方法是:板桩,钻孔桩墙,泥浆墙。 土地固定系统的选择是由技术性能要求和施工可行性(例如手段,方法)决定的,包括执行的可靠性,而成本考虑了这些之后,其他问题也得到解决。通常环境后果(用于处理废泥浆和钻井液如监管要求)也非常被关注(邱阳、1998)。 土地固定系统通常是建设项目的较大的一个组成部分。如果不能按时完成项目,将极大地影响总成本。通常首先建造支撑,在许多情况下,临时支撑系统是用于支持在挖掘以允许进行不断施工,直到永久系统被构造。临时系统可以被去除或留在原处。 打桩时,因撞击或振动它们可能会被赶入到位。在一般情况下,振动是最昂贵的方法,但只适合于松散颗粒材料,土壤中具有较高电阻(例如,通过鹅卵石)的不能使用。采用打入桩系统通常是中间的成本和适合于软沉积物(包括粘性和非粘性),只要该矿床是免费的鹅卵石或更大的岩石。 通常,垂直元素(例如桩)的前安装挖掘工程和水平元件(如内部支撑或绑回)被安装为挖掘工程的进行下去,从而限制了跨距长度,以便减少在垂直开发弯矩元素。在填充情况下,桩可先设置,从在斜坡的底部其嵌入悬挑起来,安装作为填充进步水平元素(如搭背或土钉)。如果滞后是用来保持垂直元素之间的土壤中,它被安装为挖掘工程的进行下去,或之前以填补位置。 吉尔- 马丁等人(2010)提供了一个数值计算程序,以获取圆形桩承受轴向载荷和统一标志(如悬臂桩)的单轴弯矩的最佳纵筋。他们开发的两种优化流程:用一个或两个直径为纵向钢筋。优化增强模式允许大量减少的设计要求钢筋的用量,这些减少纵向钢筋可达到50%相对传统的,均匀分布的加固方案。 加固桩集中纵向钢筋最佳的位置在受拉区。除了节约钢筋,所述非对称加强钢筋图案提高抗弯刚度,通过增加转动惯量的转化部分的时刻。这种增加的刚性可能会在一段时间内增加的变形与蠕变相关的费用。评估相对于传统的非对称加强桩的优点,对称,钢筋桩被服务的条件下全面测试来完成的,这种试验是为了验证结构的可行性和取得的变形的原位测量。 基于现场试验中,用于优化的加强图案的优点浇铸钻出孔(CIDH)在巴塞罗那的

乡村旅游与可持续发展【外文翻译】

外文翻译 译文 标题:乡村旅游与可持续发展 资料来源: 亚诺什学院 - 布达佩斯经济科学大学 作者:塔玛拉拉茨 - 拉斯洛坡格左 引言 乡村旅游是旅游产业的一个部分,这在匈牙利显得尤为重要。在一个国家没有壮观的自然景观,没有海滨、高山、雨林、珍奇动物的情况下,迷人的村庄、温泉、河流和湖泊这些旅游资源可以利用起来。优美环境与当地人们传统的热情接待相结合,能够提供给游客愉快的体验,让游客在安静的环境中得到放松并且欣赏到文化景观。 一方面,乡村旅游业的发展使匈牙利旅游资源呈现多样化,使国家形象更加多姿多彩。另一方面,乡村旅游是刺激经济增长的一种手段,促进了欠发达地区的产业发展,并改善当地居民的生活水平。 如果乡村旅游要发挥其真正的作用,在某种程度上得到进一步的发展,那么在其自身发展的基础上,就要确保资源的长期可持续性发展。那么,什么是乡村旅游的可持续发展方式?如何对其可持续性进行监测来达到促进农村发展的目的?本文试图回答这些问题,并且通过提出匈牙利乡村旅游指标来了解被认为是这种类型的旅游的目前情况。 旅游业可持续发展 可持续发展的概念是由世界环境与发展委员会在1987年的布伦特兰报告中关提出来的,可持续发展定义为“发展,以满足当代人的需求又不损害子孙后代能满足自己的需要”。 旅游业是世界各地最重要的经济活动之一,1997年世界各地国际运送超过6.17亿人,年收益产生448亿美元(WTO,1998年),这是一个重要的经济力量。1996年产生生产总值3153.3亿美元,为255万人创造就业机会,参与生产应用程序。旅游业生产值占到世界10.7%的国内生产总值,766亿美元用于投资应用程序,每年都

项目成本控制 一、引言 项目是企业形象的窗口和效益的源泉。随着市场竞争日趋激烈,工程质量、文明施工要求不断提高,材料价格波动起伏,以及其他种种不确定因素的影响,使得项目运作处于较为严峻的环境之中。由此可见项目的成本控制是贯穿在工程建设自招投标阶段直到竣工验收的全过程,它是企业全面成本管理的重要环节,必须在组织和控制措施上给于高度的重视,以期达到提高企业经济效益的目的。 二、概述 工程施工项目成本控制,指在项目成本在成本发生和形成过程中,对生产经营所消耗的人力资源、物资资源和费用开支,进行指导、监督、调节和限制,及时预防、发现和纠正偏差从而把各项费用控制在计划成本的预定目标之内,以达到保证企业生产经营效益的目的。 三、施工企业成本控制原则 施工企业的成本控制是以施工项目成本控制为中心,施工项目成本控制原则是企业成本管理的基础和核心,施工企业项目经理部在对项目施工过程进行成本控制时,必须遵循以下基本原则。 3.1 成本最低化原则。施工项目成本控制的根本目的,在于通过成本管理的各种手段,促进不断降低施工项目成本,以达到可能实现最低的目标成本的要求。在实行成本最低化原则时,应注意降低成本的可能性和合理的成本最低化。一方面挖掘各种降低成本的能力,使可能性变为现实;另一方面要从实际出发,制定通过主观努力可能达到合理的最低成本水平。 3.2 全面成本控制原则。全面成本管理是全企业、全员和全过程的管理,亦称“三全”管理。项目成本的全员控制有一个系统的实质性内容,包括各部门、各单位的责任网络和班组经济核算等等,应防止成本控制人人有责,人人不管。项目成本的全过程控制要求成本控制工作要随着项目施工进展的各个阶段连续 进行,既不能疏漏,又不能时紧时松,应使施工项目成本自始至终置于有效的控制之下。 3.3 动态控制原则。施工项目是一次性的,成本控制应强调项目的中间控制,即动态控制。因为施工准备阶段的成本控制只是根据施工组织设计的具体内容确

外文翻译--生态旅游对环境的影响

生态旅游对环境的影响(节选) 原文来源:Environment Impacts of Ecotourism;Edited by Ralf Buckley International Centre for Ecotourism Research,Griffith University,Australia CAIB Publishing;Oct,2008 生态旅游由于其实际或潜在的积极影响受到社会和保护区以及公司和消费者广泛吹捧。例如,在讨论进入保护区方面,旅游说客和生态旅游经营者宣称他们不仅将会采取措施师环境影响减到最小,而且生态旅游还会产生利益。然而,保护区也为旅游业提供了非常重要的好处。 每年被人类消耗或污染的自然资源有很多。人类生存需要饮用水,可呼吸的空气和可用的生物多样性。自然生态系统是每个这些领域的主要的蓄水池。生态系统由于人类活动已被不同程度地广泛地修改了。近原始的荒野地区和其他小改造的地区的环境正在不断减少,像城市中心,垃圾堆放场,矿场和单一种植区几乎完全修改的环境在继续扩大。有很多没有完全修改而又很重要的地方,如农村住宅,布罗德埃克牧区和被采伐的原始森林在最少修改的地区也继续扩大。为制止和扭转这些趋势,只在人类的社会结构和人类行为发生大规模和深远的变化时才能成为可能。然而,如果在短期内没有这种变化,规模更大的混乱将逼近人类。 关于可持续能力和关乎人类生存的任何长期策略唯一最重要的组分,能够使世界各种各样的生态系统的代表性区域保持在一个合理的原封不动的和功能的状态。当然,这是保护区全局系统的主要目标,包括世界遗产地区、生物圈储备、国家公园和其他保护区域。然而,这些公园还不能独自地防止生物多样性持续损失:首先,因为他们是太小和不充分地代表性的;第二,因为他们不充分地被保护。目前,有公开和私有土地其他地区在被保护区系统之外的,它们对保护生物多样性和空气和水的质量有很大贡献。它们包括:像极地,高山,沙漠和海洋生态系一样很少人的地方;那些为木材和家畜产品使用的但其中很少使用牧场保留其原有的性质功能和生物多样性的森林地和牧场;人类的生活方式没有介入对自然环境的密集的修改的部族和社区土地。然后,随着人口和资源消耗量的继续增长,所有这些未保护的区域却受到越来越多的开发和修改,例如采伐,农业清除和类似的冲击加速。特别是,其中一些区域涉及保护和储备,而且逐渐增长的人口压力正在导致土地清除和移民直到储备界限,有时会在保护的过程中出现侵犯。在被保护区界限不是明确界定或没有发现的地区,这样侵犯也许一般包括偷猎,非法收获,小规模移民和时而的军事演习。然而,甚而在国家公园界限已建立和强制执行的区域,侵犯可能仍然发生。有时,相关的立法也许允许发展某些类在公园界限之外的可能在保护区的周长附近增加杂草、病原生物、野生动物、水污染和火来源的压力,并且这些能不再人类进一步的干涉下在保护区里得到传播。 因此,代表性的生态系统的保护不仅能够通过增加保护区财产,改进现存储备的有效保护率,而且通过减少对储备区以外土地的修改得到改进,以便改进它的保护价值。 用纯粹财政术语来说,以现在的市场价购买高保护价值所有剩余的区域,在更加富有的政府和公司看来是在世界范围内的,并且宣称他们作为保护区。然而,由于许多政治原因,这是不太可能发生得。许多保护区管理代办处没有足够的金钱来管理他们现有的财产,更不用说发展它。全世界国家公园和相似的储备总面积继续慢慢地增长,并且在最近几年里给保护区的管理代办处的一些资助增加显著。然而,在全球范围内,公共的保护区越来越资金短缺。同时,他们不断地受到人类的压力,这种压力同时来自于从在它们的边界之外的压力和游客的人数和期望增长的压力。结果,只有最大和最远的保

关于生态旅游的文献综述

关于生态旅游的文献综述 摘要:生态旅游作为一项以保护性、教育性和责任性为主要特征的旅游活动,在生态环境问题日趋严重的今天,显示出越来越大的生命力,目前生态旅游已成为世界各国旅游者的一种时尚和旅游业的热点。生态旅游迅速的发展,已成为当今旅游发展的重要方向。本文对生态旅游的产生背景,概念内涵以及特性、国内为发展概况等研究文献进行了综述。 关键词:生态旅游内涵特性国内外发展 一.引言 在全球人类面临生存的环境危机的背景下,随着人类环境意识的觉醒,绿色运动及绿色消费已席卷全球。生态旅游作为一种绿色旅游消费,一经提出便在全球引起巨大反响,短短几十年的今天,生态旅游的概念迅速普及到全球,其内涵也得到了不断地充实,针对目前生态环境的不断恶化的状况,旅游业从生态旅游的对象是自然景物出发,将生态旅游定义为“回归大自然旅游”和“绿色旅游” [1]。作为一个综合性的服务部门和第三产业的重要构成部分,旅游业以其强大的关联和带动作用,在区域乃至国家经济社会发展中的作用日记重要,促使诸多地区将旅游业作为支柱性产业或主导性产业加以培育和发展,致使区域间旅游发展竞争日趋激烈[2]。针对现在旅游业发展中出现的种种问题,旅游业从生态旅游的对象不应受到损害出发,将生态旅游定义为“保护旅游”和“可持续发展旅游”。同时,世界各国根据各自的国情开展生态旅游,形成各具特色的生态旅游[3]。 二.生态旅游概述 当今世界经济中,服务业是增长最快的产业,也是提供就业机会最多的产业,美国学者约翰·奈斯比特在他的《2000年大趋势和全球问题》中提出,21世纪世界服务经济的领导产业,主要是电信业,信息技术产业和旅游业三种主要的服务业。1992年里约热内卢会议后,生态旅游在全球得到迅速发展,它作为旅游业中一种宣传主题明确,生命力旺盛的旅游形式,日益深入人心,为了更好的发展生态旅游,先对生态旅游做一回顾。 1生态旅游产生的背景 生态旅游英名为Ecotourism是Ecological Tourism的缩写,由国际自然保护联盟专家H.ceballos Lascurain于1983首次提出的。它不仅被用来表征所有观光景物的旅游,而且强调观光的对象不应受到损害,是在可持续管理的思想指导下开展的旅游活动[4]。它的产生有以下几种原因: (1)有可靠的理论基础。生态学和可持续发展的思想为生态旅游的产生奠定了深厚的基础,现生态学已超过了传统生物生态学的范畴,成为一种人类普遍的思想和原则。在生态利益优先的趋势下,在可持续发展理论指导下,人们开始注重用生态学原理,设计良性运转的旅游系统,实施生态工程,促进了生态旅游的

不是说富于想象力的结构设计就能够创造出伟大建筑。正相反,有许多例优美的建筑仅得到结构工程师适当的支持就被创造出来了,然而,如果没有天赋甚厚的建筑师的创造力的指导,那么,得以发展的就只能是好的结构,并非是伟大的建筑。无论如何,要想创造出高层建筑真正非凡的设计,两者都需要最好的。 虽然在文献中通常可以见到有关这七种体系的全面性讨论,但是在这里还值得进一步讨论。设计方法的本质贯穿于整个讨论。设计方法的本质贯穿于整个讨论中。 抗弯矩框架 抗弯矩框架也许是低,中高度的建筑中常用的体系,它具有线性水平构件和垂直构件在接头处基本刚接之特点。这种框架用作独立的体系,或者和其他体系结合起来使用,以便提供所需要水平荷载抵抗力。对于较高的高层建筑,可能会发现该本系不宜作为独立体系,这是因为在侧向力的作用下难以调动足够的刚度。 我们可以利用STRESS,STRUDL 或者其他大量合适的计算机程序进行结构分析。所谓的门架法分析或悬臂法分析在当今的技术中无一席之地,由于柱梁节点固有柔性,并且由于初步设计应该力求突出体系的弱点,所以在初析中使用框架的中心距尺寸设计是司空惯的。当然,在设计的后期阶段,实际地评价结点的变形很有必要。 支撑框架 支撑框架实际上刚度比抗弯矩框架强,在高层建筑中也得到更广泛的应用。这种体系以其结点处铰接或则接的线性水平构件、垂直构件和斜撑构件而具特色,它通常与其他体系共同用于较高的建筑,并且作为一种独立的体系用在低、中高度的建筑中。

外文文献 RURAL TOURISM AND SUSTAINABLE DEVELOPMENT INTRODUCTION Rural tourism is a segment of the total tourist industry which is particularly important in Hungary, in a country with no spectacular natural attractions, without seaside, high mountains, rainforest or herds of exotic animals. However, its attractive cultural landscapes with small villages, thermal springs, rivers and lakes, combined with the traditional hospitality, are able to offer pleasant experiences to the kind of tourist who is looking for relaxation and recreation in a calm setting. On one hand, rural tourism development can play an important role in the diversification of the Hungarian tourist supply and in the creation of a more complex and colourful country image. On the other hand, rural tourism is not only the end, but the means to stimulate economic growth, to increase the viability of underdeveloped regions, and to improve the living standards of local populations. If rural tourism is to fulfil all these roles, it has to be developed in a way that ensures the long-term sustainability of the resources and that of the development progress itself. But what is a sustainable way of development in rural tourism ? How can sustainability be monitored and promoted in rural destinations ? This paper attempts to answer these questions by presenting the current situation of Hungarian rural tourism through indicators that are considered to be relevant for this type of tourism. SUSTAINABLE TOURISM DEVELOPMENT The concept of sustainable development was introduced by the World Commission on Environment and Development in the Brundtland Report in 1987, defining sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs". Tourism is one of the foremost economic activities around the world, having transported more than 617 million people internationally and generated 448 billion USD in receipts in 1997 (WTO, 1998). It is a major economic force, having generated in 1996 an estimated 3,153.3 billion USD in gross output, creating employment for app. 255 million people, producing app. 10.7 per cent of world gross domestic product, investing app. 766 billion USD in new facilities
