Elastoplastic analysis of surrounding rock in weakly cemented soft rock roadways and its support practice

Abstract The effects of rock softening and shear dilation in the plastic zone are considered to examine the stability of the surrounding rock in deeply buried and weakly cemented soft rock roadways. An elastic-soft fracture mechanical model of the surrounding rock is developed, from which the analyt...
