    THE MAIN GEOLOGICAL HAZARD PROBLEM FACED DURING UNDERGROUND SPACE EXPLOITATION AND PREVENTION COUNTERMEASURE IN CENTRAL CITY ZONE IN SHANGHAI

    • 摘要: 上海市中心城区地下空间开发力度日益加大,所面临的地质灾害问题亦愈发突现。本文就上海市地下工程施工中可能出现的地质环境问题及适宜性进行了分析,主要包括砂、粉性土所引起的流砂问题、地下水引起的基坑突涌问题、软土变形问题、土层土性变化问题等,并提出了防治对策措施,对地下空间规划及建设提供了参考依据。

       

      Abstract: Now the exploitation velocity of underground space is increasing day and day, and the geological hazard problem produced by that appeared gradually. This paper firstly described the geological background of central city zone, then analyzed the geoenvironmental poblem produced during construction of underground project and usable feasibility. These problems include shifting sand conduced by sand and silty soil, and water inrushing of foundation pit conduced by underground water, and soft soil foundation deformation problem, and soil layer variational problem. Finally this paper advanced corresponding prevention countermeasure, which provided reference for plan and construction of underground space.
