深基坑工程的空间性状分析

Spatial behavior analysis of deep excavation

  • 摘要: 用三维空间有限单元法研究了基坑开挖过程中围护结构变形、土压力的空间分布及基坑的几何尺寸效应,并与按二维平面问题分析的结果进行了比较。通过对杭州市某基坑工程的实例分析,验证了对基坑工程进行三维分析的必要性以及计算模式的合理性。

     

    Abstract: In this paper, 3 D FEM is used to analyse the spatial distribution of deformation, earth pressure and the size effect of deep excavation, and the results calculated with 3 D FEM and 2 D FEM are compared. Finally, through an excavation case in Hangzhou, the necessity of 3 D analysis and the reasonableness of the calculating model were verified.
