建筑物超载作用下的基坑变形分析

Analysis of the Foundation Pit Deformation under Building Overloading Force

摘要:

结合上海某地铁车站基坑工程，对基坑出现险情期间的监测数据进行详细分析，初步探讨了险情出现的原因。结果表明邻近建筑物超载对基坑变形有显著的影响，并得到基坑和建筑物的大变形具有同时性和突然性的特征，对类似工程具有一定的借鉴意义。

Abstract:

The monitoring data of one subway foundation pit engineering in shanghai was analyzed in detail and the possible reasons of the potential accident were primarily discussed. The result shows that the building overloading has prominent influences on the deformation of the foundation pit, and that the deformation of the building and foundation pit has the characters of simultaneity and suddenness, which can give some reference for the similar engineering works.
