In this study, a new numerical model of ring shear tester for shear band soil of landslide was established. The special feature of this model is that it considers the mechanism of friction-induced thermal pressurization, which is potentially an important cause of high-speed catastrophic landslides. The key to the construction of this numerical ring shear model is to realize the THM (thermo-hydro-mechanical) dynamic coupling of soil particles, which includes the processes of frictional heating, thermal pressurization, and strength softening during shearing of solid particles. All of these are c...
