FEM-BASED SECONDARY DEVELOPMENT OF GEO-MATERIAL CONSTITUTIVE AND ITS APPLICATIONS

摘要：

Duncan-Chang E-v is used widely in civil engineering field for the reason of clear conception and simple physical meaning.We can use the user material subroutine UMAT which is provided by the FEM software ABAQUS as a second development flat,and use the Fortran language for programming of Duncan-Chang E-v nonlinearity constitutive model.Then the nonlinearity of rock and soil can be easily expressed.In order to verify the validity of the program,the model is applied in a sedimentation analysis of high embankment.
