Effect of unloading confining pressure rates on macroscopic and microscopic mechanisms in diorite based on PFC3D
IntroductionDeep underground excavation induces significant unloading damage in diorite, yet micromechanical mechanisms under varying unloading rates remain poorly understood.MethodsHerein, we employed the discrete element method to investigate the microscopic and macroscopic response mechanisms of...
