摘要
本文用有限单元法分析了基坑开挖的三维性状，探讨了基坑围护结构变形、地面沉降及土压力分布规律，并与二维分析结果进行了对比分析，得出了一些有益的结论，供工程实践参考．
This paper using FEM analyses the three dimensional(3 D) behaviour of excavation,and discusses the distribution of the deformation of retaining wall,ground settlement and earth pressure.The results have been compared with 2 D behavior,and some valuable conclusions are drawn.It is hoped that this paper might be a reference for engineers.
