Modeling Roughness of Rock Discontinuity Surfaces
… quantifying the rock discontinuity condition of roughness through the physically based modeling approach of signal analysis. The development of this method came about after investigation into the use of qualitative categorizations of roughness from the RMR rating system within rock engineering …

Stability of Coastal Cliffs along the Pembrokeshire Coast National Park
… uniaxial compressive strength were comparable. Joint roughness coefficient (JRC) obtained from tilting tests suggested that standard equations were more applicable to situations of low roughness rock with low normal strength.Failure modes for cliffs of the western Coal Measures were mainly …

Enhanced Laboratory Testing and Characterization Related to the Mechanics of Anisotropic Rock
… the unconfined compressive strength test, and joint deformation is measured via the direct shear test. However, the testing methods were historically designed for rock materials that were homogenous and isotropic. This research addresses the limitations of some of the most common laboratory …

Characterization and modeling of the stress and pore-fluid dependent acoustic properties of fractured porous rocks
… opposite two points by sharp guillotines. The Joint Roughness Coefficient (JRC) values of the fractured core samples were determined by profilometry and tilt test. The effect of mismatching of the fracture surfaces on shear wave splitting was investigated by applying different amounts of shear …
