Abstract

The creep of soft rocks induced by seepage-stress coupling is one of the critical factors that causes the failure of the rock. However, the actual failure mechanisms of soft rocks, particularly during the accelerated creep stage, have not been fully understood so far. Therefore, the purpose of the present study is to develop theoretical models to quantitively investigate the effects of coupled fissure-pore seepage and hydro-mechanical coupling on the damage behavior of soft rocks. The evolution model of coupled fissure-pore seepage in soft rock was developed, and the coupled fissure-pore damage creep model of soft rock was established. The developed models were also validated by performing a..
