# 基坑开挖深度对邻近建筑物的影响Influence of Excavation Depth of Foundation Pit on Adjacent Buildings

Abstract:
Combining with the measured data of bund tunnel project, the effect of excavation depth on the adjacent buildings is studied by using the three-dimensional fast Lagrange analysis program—FLAC3D. In the process of numerical analysis, the excavation of foundation pit is carried out by the way of sub layer, and the supporting role of vertical support structure is realized by improving the parameters of surrounding soil. By numerical simulation results, the deformation law of building settlement caused by excavation depth is obtained, which can be based on the allowable deformation value of the foundation pit to evaluate the influence of foundation pit excavation on the building.
