... are tested in laboratory. Test results shows that the peak shear strength (τ) of rock joints is anisotropic in nature due to change in morphological features in particular shearing direction. Joint roughness coefficient (JRC) is determined in each shearing direction by trial and error method using Barton's...

... ABSTRACT In this study, Barton's profiles are investigated precisely to clarify the validity of JRC and a new method that quantifies the JRC is proposed. Laser profilometer and the direct shear strength testing system that simulates the in-situ stress and the boundary conditions have been...

... An original concept of JRC-diagram that can evaluate JRC and its size-effect by using a fractal model was proposed. In order to confirm the applicability of the JRC-diagram, first, JRC of the tensile fracture surfaces of a granite and a sandstone were evaluated by both the JRC-diagram...

... ABSTRACT: Socket resistance contributes significantly to pile capacity. In the present work, an approach is presented for estimating the capacity of side-resistance-only piles socketed in rock by considering the effect of interlocking in terms of JRC and Fractal Dimension. Unlike available...
