摘要
介绍有限元运用于软土深基坑开挖的计算原理.利用三维有限元建模后,通过桩土相互作用分析,对影响深基坑变形和稳定的关键性状进行讨论,从而提出了一些控制支护结构变形,保持基坑稳定的方法措施.
In this paper, the theory of finite element method is introduced. Three-dimention finite element analysis is carried out in which the excavation process is considered. The sensitive analysis of ciritical parameter is discussed in detail. The analysis result shows that investigation of simulation of excavation process is necessary in such complex problem. At last, some measures are provided to cotrol the deformation of suppotring structure and keep stability of foundation pit.
