摘要
地下水位的变化导致土体的工程力学性质改变,严重的导致基坑失效,地下水位变化对基坑稳定性具有重大的意义。结合某基坑工程地下水位变化导致城市污水管道侧移变形引起管道失效,根据地下水位监测变化情况,利用大型岩土工程软件FLAC,对基坑失效进行了数值模拟分析,得出相关结论,对工程具有一定的指导意义。
The change of the subsoil water level may result in the mechanics change of the soil mass and the failure of the foundation. Therefore it is significant for the stability of the foundation. A case of the subsoil water change in a deep foundation project was studied, which resulted in the sewage conduit distortion and failure. Based on the monitoring data of the subsoil water level and the property of the soil, the simulation of the foundation failure was conducted by FLAC. And the results can give reference for the projects.
