摘要
将Duncan-Chang模型引入饱和-非饱和土的本构关系模型,建立了饱和-非饱和土的统一的非线性弹性模型,并应用于降雨滑坡的机理分析。由实例分析得知,利用饱和-非饱和土的统一的非线性弹性模型来分析由于大气降雨而引起的土体滑坡的形成与发展过程是可行的,也是一种有益的探索。
Duncan-Chang model is introduced into the constitutive relationship of saturated-unsaturated soils,and the nonlinear elastic model for this kind of soils is established,and is used for the analysis on the landslide during rainfall. Example analysis shows that it is feasible and beneficial to use this model for the analysis of soil landslide during rainfall.
