Abstract

At present, the thermo-hydro-mechanical coupling in unsaturated porous media is an interested subject since the environmental issues have been raised worldwide. Thus, this paper presents simulation results of effects of temperature and suction on undrained shear strength of unsaturated porous media, which is an important parameter in geotechnical design and analysis. The equation of undrained shear strength including thermal effect was used to estimate the results at various temperatures and matric suctions. Typically, the results show that the undrained shear strength decreases with increasing temperature for all values of matric suction. However, the undrained shear strength increases with increasing matric suction for all values of ambient temperature.
