... triaxial creep tests The creep properties of sandstone under different conditions are compared and analyzed The test results show that: in the case of same confining pressure, pore pressure can increase the instantaneous elastic deformation and creep deformation but reduce the strength of sandstone...

... Abstract Following the previous work about the relation between permeability evolution and rock creep deformation [1–2], triaxial creep tests of volcanic breccias under various seepage pressures were performed on rock specimens and their lateral deformation behavior in the accelerated creep...
