摘　　要： 发展了一个可模拟基坑开挖过程的非线性有限元程序。在此基础上，针对某深基坑开挖问题，分析了开挖过程中挡土结构上土压力的分布和发展规律，并研究了土体固结对土压力的影响，初步探讨了挡墙刚度等其它因素对挡土结构主、被动区土压力的影响，得出较有意义的结论，并对一基坑工程实例进行了分析。 In this paper,a program of nonlinear finite element method was developed in order to simulate the behavior of excavation.An excavation case is used to investigate the distribution and development of earth pressure behind or in front of retaining wall.The influences of some factors such as consolidation,strut stiffness,wall stiffness and embedded length of the wall on earth pressure are studied.The differences between calculation and the field observation of earth pressure on the retaining wall of an excavation in Hangzhou are also analyzed.

关 键 词： 基坑开挖 挡墙 土压力 有限元
