In order to revel the hydro-mechanical coupling characteristics of granite at various pore pressures and confining pressures. The spatial micro-pore structure before and after the failure of granite is extracted by high-precision CT scanning system. The results show that the UCS of the damaged granite decreases with the increase of pore pressure under certain confining pressure. https://www.spidertattooz.com/Orly-Nail-Lacquer-Ethereal-Plane-2000025-p28581/
