工程测量新技术、新方法在地铁施工中的应用

Applying New Engineering and Survey Methods in Subway Construction

文章介绍了当前地铁工程测量的现状和一些工程测量新技术、新方法。并从地下铁道工程测量精度设计的原则和要求、定向测量GPS控制网测量、铺轨基标测量等方面 ,论证了提高地铁施工精度和施工质量的新途径。

The paper first introduces the present system in use for subway construction and then goes on to discuss some new engineering and survey methods. The author argues that the new techniques and methods serve as a means for improving the precision and quality of subway construction. Improvements emerge through: the principle and demand of precision design for subway engineering surveys; orientation surveys of GPS control networks; and the track-laying fiducial mark surveys.
