... confirmed to exist from stereonet analysis. The JRC value of the major joint set was evaluated to be 11.2±2.8. For the 16 joints selected arbitrary, the JRCs obtained from image processing and real measurement on the joint surface in the rock core were compared for validation of this new method. As JRC...

... on the strength of joints, various researchers have proposed different equations and correlations to estimate strength parameters. This paper briefly describes a new approach to characterize the three-dimensional morphology of rough joint surfaces and proposes a new equation to evaluate the peak shear strength...

... closure test on model joints is performed to evaluate the applicability of this mathematical model. INTRODUCTION The shear behavior and flow conductivity of rough joints is primarily dominated by the contact of joint asperities. Two joint surfaces pressed together approach each other owing...
