Coupled hydromechanical responses around a roadway excavation in inclined coal–mudstone strata

Chenxi Zhao, Fuqiang Gao, Qinghua Lei, Shuangyong Dong et autres

Abstract We conduct a numerical investigation into the spatio-temporal evolution of excavation-induced disturbances around roadways in inclined coal–mudstone strata containing fracture networks. The intact rock is modeled using a Mohr–Coulomb plastic constitutive law to capture deformation and failure, while the displacement of …

Hygroscopic weakening accelerates the transition to catastrophic failure during brittle creep in clastic rocks

Rui Wu, Hongpu Kang, Fuqiang Gao, Xiangyuan Peng et autres

Understanding how water influences slow fracture growth in rocks remains a major gap in our ability to predict time-dependent failure. In particular, it is still unclear how moisture-related weakening push a subcritically stressed rock from stable deformation into sudden collapse.In this study, …
