Mechanical properties and energy evolution and the applicability of strength criteria of sandstone under hydro-mechanical coupling

To explore the hydraulic coupling characteristics of rocks, triaxial compression tests on water-saturated sandstone under hydro-mechanical coupling were carried out using the MTS815 rock mechanics test system. The test confining pressures were 10, 20, 30 MPa. Under each confining pressure, according...
