Abstract：Based on laboratory unsaturated experimental results of argillite, the extension models of hardening plasticity, Hoek-brown and Mohr-Coulomb failure criteria to include unsaturation in porous media is presented. The developed models are applied to simulate the evolution law of unsaturated water flow in surrounding rock mass and concrete support of an argillite shaft considering of excavation and ventilation. The numerical results show that the in situ stress and hydraulic parameters water relative permeability has high dependence on water transport and sizes of unsaturated zone in rock mass, especially the water relative permeability.
