The freeze-thaw damage of rock is mainly induced by cycling loading of pore ice pressure and thermal stress under coupled thermo-hydro-mechanical (THM) condition at low temperature. The accuracy and correctness of coupled T-H-M model for freezing rock are controlled by critical parameters including unfrozen water content, ice pressure, permeability, and the equivalent thermal conductivity.
