Abstract.This study investigates the creep behavior and crack evolution characteristics of rock under axial pressure and shear loads using the Particle Flow Code (PFC2D) software. The results show that the rock exhibits typical three-stage creep behavior, including transient creep, steady-state creep, and residual stability stages under both axial pressure and shear load. Under axial pressure, the displacement decay rate is slower, with compression-dominated deformation and significant suppression of crack propagation due to the confining pressure. This delays the occurrence of accelerated creep. In … Read more →
