Abstract: The simple yield standard is used to determine the damage variables frozen soil, therefore Xiyuan Model viscoplastic creep is repaired.The constitutive function of the viscoelastic plastic damage-coupling is deduced.The viscoelastic plastic damage-coupling constitutive model for geo-materials is embeded into the commercial FEM software ADINA as a user's subroutine.FEM analysizing suggest that the model is of the feature of the non-linear accelerative creep frozen soil, and can be used for engineering practice.
