Abstract
Rock joint roughness coefficient (JRC) is an important parameter to determine the shear strength of unfilled hard rock joints. It is of great significance to acquire a representative value of JRC. For irregular undulated joints, the JRC has a strong directivity and surface inclination can reflect the roughness difference under the condition of cyclic shear. Considering Barton's standard joint roughness profiles as an example, the secant angles...
