摘要：
In this paper, a permeability parameter calculation model with six influence coefficients is constructed by taking volume strain and equivalent strain under CoulombMohr 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.
