Creep failure characteristics and damage creep model of red layer soft rock based on Perzyna viscoplastic theory

Abstract Rock creep is essentially a process of damage accumulation. According to the damage evolution of rock under creep conditions, the TAW2000 triaxial test system is used to carry out triaxial creep test on red layer soft rock taken from Yibo Tunnel in Leshan, Sichuan Province, China, and analy...
