摘要：
In this paper, a permeability parameter calculation model with six influence coefficients is constructed by taking volume strain and equivalent strain under Coulomb -Mohr criterion as independent variables. The optimal estimates of permeability parameter influence coefficients are applied to the prediction of permeability parameters under a complex loading path, and the prediction results verify the applicability of the model.
