Analysis of the Adjacent Building Influence on Foundation Pit Deformation
-
摘要: 针对上海某地铁车站基坑工程施工中存在的安全隐患,结合地质水文资料,对基坑围护墙体及邻近建筑物的监测数据进行了分析,结果表明邻近建筑物对基坑变形有显著的影响,邻近建筑物的超载作用以及所在土层的性质是引起这次基坑异常变形的原因,对其他类似工程具有一定的参考价值。Abstract: Combined with the potential insecurity of one subway foundation pit engineering, the monitoring data of foundation pit support wall and the adjacent building is analyzed on the basis of geological documents. It is found that the adjacent building has prominent influences on the deformation of the foundation pit, and the overloading of adjacent building and the stratum character of the construction field is the reason of the exceptional deformation during the excavation of foundation pit. The research has reference value for similar engineering.
