Creep Mechanics of the High-Stress Soft Rock under Grade Unloading

Creep Mechanics of the High-Stress Soft Rock under Grade Unloading

In order to study the creep behavior of deep soft rock, gritstone was chosen as the research subject, and a rock triaxial rheometer (Rock 600-50) and acoustic emission (AE) system (SH-II) were used to carry out the grade unloading confining pressure creep test under a high-stress level. The test res...
