摘　　要：采用fortran语言编写了Duncan-Chang本构模型子程序,实现了有限元软件ABAQUS的二次开发,再利用UMAT子程序接口导入Duncan-Chang的E-B本构模型对垃圾土边坡稳定性进行分析。通过与极限平衡法中的Bishop法和Morgenstern-Price法比较,对基于Duncan-Chang本构模型的有限元法在垃圾土边坡稳定性分析的合理性进行了探讨。This paper compiles the subroutine of Duncan-Chang constitutive model, secondary develop finite element software ABAQUS, and make an analysis on refuse soil slope based on Duncan-Chang E-B constitutive model introduced by using the interface of UMAT subroutine. Through comparison to Bishop method and Morgenstern-Price method, this paper have discussed the rationality of refuse soil slope analysis on the basis of Duncan-Chang constitutive model.
