... Abstract The joint surface roughness is one of the important parameters which influences the mechanical and hydro-mechanical behavior of rock joints. In most cases, the joint roughness coefficient (JRC) was used to quantitatively express the roughness degree. In this study, we applied the mean...

... were analyzed by using of fractal theory. Under consideration of the surface roughness of fractured rock, a modified generalized Kelvin model was established, which presents stable creep behavior with the characters of instantaneous deformation, retard elasticity and plastic deformation. The study...
