重庆市轻轨一号线工程埋置深度的工程地质研究

ENGINEERING GEOLOGICAL RESEARCH ON THE LAYOUT DEPTH OF LIGHT RAIL LINE 1 IN CHONGQING CITY

重庆市轻轨一号线工程布置于具有山城特色的地质环境中，埋置深度的选择是一重要问题。本文在分析工程地质特性的基础上，根据工程特点确定了选择埋置深度的原则，通过工程类比给出了最小安全覆跨比标准，并针对各车站和区间的实际情况提出了具体的埋置深度建议。

Light rail line 1 in Chongging City will be built in a geological environment characteristic of a mountainous city. Selection of its layout depth is an important problem. In the paper, Based on analysis of the engineering geological setting ,the principles for determination of its layout depth is proposed ;the standard of the minimum safe ratios of its equivalent thickess of its coverage to spen is given; and the concrete suggestion of its layout depth is put forward.
