【摘要】 上海地铁某平行换乘车站建设中,后建车站施工时由于线路限制,与已建车站共用一堵地下墙,地下墙插入比仅为0.14,远远不能满足基坑变形控制的要求,对邻近已建车站的运营安全构成极大威胁。介绍了该工程的变形控制措施,并通过现场实测数据分析了其控制效果。更多还原

【Abstract】 In constructing a parallel interchange station of Shanghai subway, the foundation pit had to share a diaphragm wall with an existing station because of environmental limits. Furthermore, The insertion ratio of this wall was only 0.14, which resulted in significant difficulties in deformation control and remarkable threat to the safe operation of the existing station. The paper gives the measures taken for deformation control, and analyzes the control results using on-site measurement data.更多还原
