摘要
用空间有限单元法研究了基坑开挖过程中围护结构变形、周围地表沉降、基坑底部隆起的空间分布以及影响围护结构变形的主要因素 。
The deformation of foundation pit during excavation is studied using 3D FEM.The deformation of retaining structures,the ground surface settlement,and the distribution of bottom ground heave are stressed to study.It is also considered for some essential influence factors on the retaining structures during excavation.A practical engineering of excavation case in Hangzhou is studied,and some useful conclusions are obtained.Such as the deformation of a foundation pit is occurred in a space-distributed manner.and the deformations in the corner of a foundation pit are smaller than that of the middle part.It is verified for that the finite element method is useful tool to solve the geotechnical problem.
