Lesson 1 Text Civil Engineering Civil engineering,the oldest of the engineering specialties,is the planning,design,construction,and management of the built environment.This environment includes all structures built according to scientific principles,from irrigation and drainage systems to rocket-launching facilities.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。Civil engineers build roads,bridges,tunnels,dams,harbors,power plants,water and sewage systems,hospitals,schools,mass transit,and other public facilities essential to modern society and large population concentrations.They also build privately owned facilities such as airports,railroads,pipelines,skyscrapers,and other large structures designed for industrial,commercial,or residential use.In addition,civil engineers plan,design,and build complete cities and towns,and more recently have been planning and designing space platforms to house self-contained communities.土木工程师们修路、建桥、打隧道，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。土木这个词来源于拉丁文，愿意是市民。1782年，英国人John Smeaton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。The word civil derives from the Latin for citizen.In 1782,Englishman John Smeaton used the term to differentiate his nonmilitary engineering work from that of the military engineers who predominated at the time.Since then,the term civil engineering has often been used to refer to engineers who build public facilities,although the field is much broader.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 kinds of civil engineer specialists may be needed.When a project begins,the site is surveyed and mapped by civil engineers who locate utility placementwater,sewer,and power lines.Geotechnical specialists perform soil experiments to determine if the earth can bear the weight of the project.Environmental specialists study the projects impact on the local area:the potential for air and groundwater(地下水地下水)pollution,the projects impact on local animal and plant life,and how the project can be designed to meet government requirements aimed at protecting 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(同时同时),structural specialists use preliminary data to make detailed designs,plans,and specifications for the project.Supervising and coordinating the work of these civil engineer specialists,from beginning to end of the project,are the construction management specialists.Based on information supplies by the other specialists,construction management civil engineers estimate quantities and costs of materials and labor,schedule all work,order materials and equipment for the job,hire contractors and subcontractors,and perform other supervisory work to ensure the project is completed on time and as specified.范围：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。当一个项目开始时，场地被土木工程师所测绘，他们给定给水排水设施和电力线路的实际位置。岩土工程专家们完成土壤实验来确定地基是否能承受工程项目的自重。环境专家们研究项目对当地的影响：潜在的空气和地下水资源的污染，工程项目对当地动植物的影响，为满足保护环境的管理要求，怎样才能把工程项目设计好。运输专家确定需要什么设施来减轻由所完成的项目所引起的对当地道路和其他运输网络的压力。同时，结构专家用预备的数据为工程项目做出详细的设计、规划，和说明。从工程的开工到结束，建筑管理专家都监督和协调着上述这些土木工程师的工作。基于其他专家所提供的信息，建筑管理土木工程师估计所需的材料和人工的数据，对所有的工作提出计划，这各工序订购材料和设备，签订承包合同和转包合同，完成其他监督工作以确保工程按期按质地完成。Throughout any given project,civil engineers make extensive use of computers.Computers are used to design the projects various elements(computer-aided design,or CAD)and to manage it.Computers are necessity for the modern civil engineer because they permit the engineer to efficiently handle the large quantities of data needed in determining the best way to construct a
