摘要
文中以上海市临港国际会议中心(一期)群坑工程为背景,分析了各类型基坑的围护形式及支撑体系。通过对比各基坑围护体变形量发现,变形量不仅与基坑深度有关,同时受到基坑面积和单边长度较大的影响;IPS支撑体系在软土地区能够较好控制基坑变形量;若按照一定的工序施工,群坑之间影响较小。为后期其它软土地区群坑项目提供参考。
Based on the group pit project of Shanghai Lingang International Conference Center (Phase I), the form and support system of various types of foundation pits were analyzed in this paper. By comparing the maximum deformation of each foundation pit retaining body, it is found that the deformation is not only related to the depth of the foundation pit, but also affected by the area of pit and the length of one side. The IPS support system can control the deformation of foundation pits well in soft soil area. If the construction is carried out according to a certain process, the influence between the group pits is small. This paper provides reference for the group related foundation pits in other soft soil area.
