道路工程专业英语-(第二版)

本书特色

本书是在原2002年出版的交通高等职业技术教育教材《道路工程专业英语》的基础上，按照教育部国家级规划教材的基本要求，进行了大幅删减、改编，由解决有无向本教材共分五大部分，section-ⅰ共16篇课文，是基于原教材内容进行的重新整合。section-ⅰ重在基本知识学习、基本词汇掌握，涉及了专业基础知识、道路专业知识、桥隧专业知识，土木工程合同、计算机、养护等相关知识；section-ⅱ、section-iiⅱ、section-ⅳ是本次修订增加的内容。section-ⅱ主要介绍了大不列颠哥伦比亚省4条公路与桥梁的修建情况，section-ⅱ既是section-ⅰ知识的运用，又是section-ⅰ一些重点词汇的加强学习；section-ⅲ主要介绍了交通工程中的常见道路标线、交通标志等；section-ⅳ介绍了一个招投标范本文件和一个合同协议文件；section-ⅴ由附录ⅰ、附录ⅱ和参考文献组成。附录ⅰ是课文中的专业词汇、术语汇总，附录ⅱ对原教材中的路桥工程专业术语汇编内容进行了适度的修正。

内容简介

Traditionally, rural highway location practice has been field oriented, that is, the bulk of thelocation party's time and effort went to measurement and observation　" on the ground. "Reconnaissance of the area was the first step; the locator, using available topographic maps andsometimes an airplane, explored the area. The aim was to search out feasible routes and determinesuch primary control points as mountain passes or suitable river crossings and to locate majorobstacles such as steep slopes. Reconnaissance of feasible routes came second; each of these wascovered on foot and rough measures of relative length, difficulty, and cost were taken. Where rate ofclimb was critical, slopes were measured with an Abney hand level or some comparable instrument.Often the locator "flagged" out the line as he went to establish control points for more detailedsurveys that might follow. The third step was for the survey party to run in the preliminary or P line,or, where necessary, two or more alternate lines. Distances and angles commonly were measured bytransit and taping methods; a profile was taken by differential leveling. Topographic features andcontours often were "hung onto" the P line. In the office, after the P line data plotted, the engineerlaid out the final location or alternate locations by studying the maps and profiles. Finally this L linewas staked on the ground and profiles, cross sections, and drainage were taken for it.
Modern location practice is usually based on photogrammetric techniques.　The parallel totraditional methods as outlined above is striking; each contains the succeeding steps of area androute reconnaissance, preliminary-line survey, and final location. The difference is that the newmethod is "office" oriented. Field work before the final location is ready for staking is primarilydevoted to the aerial survey and ground control for it, to checking out obscure or incomplete data
