The experimental study systematically investigates the fracture creep under different confining pressures and flowrates by conducting fracture flow tests in a triaxial system. In addition, the mechanisms underlying the permeability evolution were also examined to some...

Permeability evolves monotonically for smooth fractures but in a fluctuating pattern for highly roughened fractures. A...
