| 摘 要： | 上海铁路南站南广场工程所处地质条件较差,存在2个承压水含水层;基坑开挖面积大、开挖深度深;周边有重要的构建筑物需要保护。介绍了基坑围护、地基加固、井点降水、基坑开挖等施工方案,并提出了施工的具体措施。尤其是"放坡开挖、中心岛工法与局部逆作"相结合的施工方法,对类似基坑施工具有借鉴意义。

| Abstract: | The Southern Square of Shanghai Railway South Station Project is under the bad geological condition with 2 confined aquifers,large excavated area and depth excavation of foundation pit,and surrounding significant buildings being protected.The construction plans were introduced including foundation pit enclosure,foundation reinforcement well-point dewatering and foundation pit excavation,etc.Moreover,the detailed construction measures were put forward,especially the method of the combination of step-slope excavation,center island method and inverse method,which could provide reference for similar foundation pit construction. |
