Experimental and Numerical Investigations of the Dynamic Permeability Evolution of a Fracture in Granite During Shearing Under Different Normal Stress Conditions

The dynamic permeability evolution of a fracture is a key scientific problem for fluid flows in rock masses within engineering systems. Understanding the dynamic permeability evolution and its mechanism is conducive to design and operation engineering. The dynamic permeability evolution of a rough granite fracture was revealed by laboratory experiments and numerical models. The permeability evolution of six fractured samples with rough fractures...
