有限元法模拟开挖引起的基坑水平位移和邻近建筑物沉降

FEM analysis of effects about horizontal displacement and sedimentation deformation of nearby building caused by excavation of foundation pit

以徐州某采用水泥土墙支护的基坑为例,采用有限元数值模拟的方法,对基坑开挖引起的水平位移量和邻近建筑物沉降量进行了计算,并与实际监测值进行了对比分析,得到了一些关于如何控制基坑水平位移和减少基坑周边建筑沉降的结论。

This article takes a foundation pit of the retaining structure with cement - soil mixed piles as an example, uses finite element numerical simulation method to compute the horizontal displacement of the retaining wall and the sedimentation of the building and compares with the actual observation results. In the end, it gets some conclusions about how to control the horizontal displacement of the retaining wall and reduce the sedimentation of the building.
