Study on frozen soil creep constitutive of theory accounting for damage

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.
