Study on variation law of rock mass dilatancy and stress threshold during loading and unloading

Abstract In order to further understand the dilatancy phenomenon of rock, the conventional triaxial compression test and unloading confining pressure test are carried out with coarse sandstone, and the rock sample underwent single slope shear failure, and the deviatoric stress-strain curve of rock s...
