A thermo-mechanical coupled particle model for simulation of thermally-induced rock damage based on the particle simulation method was *** simulation results of three verification examples,for which the analytical solutions are available,demonstrate the correctness and usefulness of the thermo-mechanical coupled particle *** model is applied to simulating an application example with two cases：one is temperature-independent elastic modulus and strength,while the other is temperature-dependent elastic modulus and *** related simulation results demonstrate that microscopic crack initiation and propagation process with consideration of temperature-independent and temperature-dependent elastic modulus and strength are different and therefore,the corresponding macroscopic failure patterns of rock are also *** the contrary,considering the temperature-dependent elastic modulus and strength has no or little effect on the heating conduction *** results,which are obtained by using the proposed model with temperature-dependent elastic modulus and strength,agree well with the experimental *** also reveals that the rock subjected to heating experiences much more cracking than the rock subjected to cooling.
