Experimental Study on Three Dimensional Coupled Stress-Seepage Law of Single Fracture

Abstract:

Equation of three dimensional stress, seepage pressure and permeability coefficient was obtained by theoretical analysis. Applying the true triaxial rock testing system of coupled stress-seepage, seepage test of granite sample with prefabricated single fracture was made under three dimensional coupled stress-seepage. The results show that three dimensional stress have the inhibition effect on single fracture seepage, and the normal main stress, having the leading role, obviously influences the permeability coefficient; seepage pressure has the promote effect on single fracture seepage, resisting the normal main stress. Fitting formula of granite permeability coefficient was gained under coupled stress-seepage which indicated the exponential relationship between permeability coefficient and three dimensional stress and seepage pressure.
