摘要针对各种常见基坑支护方式的受力特点，采用大型非线性有限元软件ABAQUS分别建立相应的数值分析模型，对这些支护方式作用下的基坑开挖的变形情况进行比较分析，总结出各种支护方式下基坑变形规律，为基坑支护结构设计、基坑开挖及基坑变形监控量测提供参考依据。

Abstract：According to the characteristics of various kinds of supporting types of excavations, the corresponding numerical models are established by using the nonlinear finite element software ABAQUS. Compared the difference of deformation after excavation, the deformation laws of various supporting types are summarized. It may provide reference for the design and monitoring measurement of excavations.

Key words： excavation lateral wall deflection ground settlement numerical analysis
