上海地铁隧道建设中工程地质条件及主要地质问题研究

ENGINEERING GEOLOGICAL CONDITIONS AND MAJOR GEOLOGICAL PROBLEMS DURING CONSTRUCTION OF METRO TUNNELS IN SHANGHAI AREA

随着上海地铁隧道建设大规模的展开,建设中面临的工程地质问题日趋凸现。本文结合上海市特有的地质条件,分析了与地铁隧道建设相关的工程地质条件,包括工程地质结构特征及浅部含水层地下水位特征。在此基础上,对地铁车站基坑开挖以及区间隧道施工可能面临的工程地质问题进行了分析研究,绘制了市中心地区工程地质问题严重性程度分区图,可为工程设计、施工提供从参考依据。

During the construction of great amount of metro tunnels,many engineering geological problems have emerged.Based on the particular geological conditions in Shanghai area,this paper analyzes the engineering geological conditions related to the construction of metro tunnel projects.It includes structure characters of engineering geological strata and groundwater level situation of shallow aquifers.Subsequently,it studies the major engineering geological problems induced during the construction.Some division maps of engineering geological problem grade have been made out,which can be the guidance for project design and construction.
