摘要
就土体本构模型及参数、非线性分析方法的改进和计算成果三个方面，回顾国内外近２０年来的研究进展，指出存在的问题及解决的方法，针对基坑开挖特有的应力应变关系和应变集中现象，单独建立适于基坑开挖分析的土体本构模型；加强软土基坑开挖的非线性分析研究；改进有限元分析方法（如单元剖分等）；
The studies on the constitutive models and their parameters,nonlinear analysis methods and calculated results are reviewed.Some problems and their solutions are indicated.In view of stress strain characteristics and strain centralization it is necessary to build consitutive models of soils for pit excavation,to study the nonlinear analysis of the excavation,and to enhance F.E.analysis method and three dimensional study in this area.
