基于 FLAC3D的深基坑开挖变形数值模拟研究
Research on numerical simulation of excavation deformation of deep foundation pit based on FLAC3D
摘要
Abstract
Combined with practical underground project ofⅡarea foundation pit of comprehensive traffic hub of Shenyang north station , the paper simulated the process of foundation pit excavation under four different support schemes by using the finite difference software FLAC 3D ,and analyzed the displacements of slope top and bottom of foundation pit and horizontal displacement of foundation pit wall caused by four types of excavation process .The simulation results show that the bottom uplift is caused by the vertical unloading ,the concrete support pile and pre -stressed anchor cable can effectively control the deformation of foundation pit .The research results and engineering practice prove that support scheme of the project is effective and feasible .关键词
