..., and the peak shear strength of the specimen is determined by the weaker joint. In contrast, under higher normal stress, the peak shear strength is attained when the tensile fractures initiate in the interlayer rock, and it has also relevancy to the JRC of double joints and interlayer thickness. Additionally...

... properties (shear strength, joint dilation, shearing stiffness, peak shear displacement, etc.) depended on the surface roughness of the joint characterized by the JRC , the normal loading applied and the loading cycles. These can be helpful when investigating the weak nature of rock slopes under dynamic...

... Abstract The shear strength of concrete-rock interfaces, used in reliability-based analyses of sliding stability of concrete dams, is commonly quantified using a simplified version of the Mohr-Coulomb shear strength criterion. This criterion is based on the assumption of a mean value driven...

... progressively increases loading of the cyclic shear stress amplitude. Test specimens were natural rock discontinuities sampled from bored-cores and artificial discontinuities made by mortar. From these tests results, the dynamic shear strength exceeds the static shear strength for rough natural rock...

...°; however, the trends of dilation angle varied with shear rate are different with asperities 15° and 30° as a result of varieties of failure modes. The increasing tendency of the slope of shear strength envelopes is related to the raising of shear rate. In order to distinguish the influences of normal...

ABSTRACT Roughness of rock joint surfaces is known to be one of the most significant factors to determine the shear strength of joint surfaces, and it has been widely investigated in various ways. A recent research on roughness quantification of rock joints revealed that various 3-dimensional...
