Correlation between Joint Roughness Coefficient (JRC) and statistical roughness parameters [PDF]
Engineering Geology and Geotechnics: Building for the Future, Proceedings of the Conference EUROENGEO 2024Rocks are polycrystalline, heterogeneous, and anisotropic media containing discontinuities that often create planes of weakness. These discontinuities influence the mechanical behavior of the rock mass through their surface morphology, their aperture, and their filling material.

Estimating the joint roughness coefficient of discontinuities found in metamorphic rocks [PDF]
Bulletin of Engineering Geology and the Environment, 2008 The paper presents the results of different methods of determining the roughness of joints in quartzites, metagreywackes and phyllites obtained from road cuts in central Portugal. The evaluation of the joint roughness coefficient (JRC) was carried out using graphical and analytical procedures.

Journal of Rock Mechanics and Geotechnical EngineeringThe scale effect on shear strength of rock joints is well-documented. However, whether scale effects are negative, positive, or even exist or not is still controversial. Joint roughness significantly influences the shear strength of rock joints. Compared

A Novel Discontinuity Roughness Parameter and Its Correlation with Joint Roughness Coefficients [PDF]
Energies, 2021 Joint roughness determination is a fundamental issue in many areas of rock engineering, because joint roughness has significant influences on mechanical properties and deformation behavior of rock masses. Available models suggested in the literature neglected combined effects of shear direction, scale of rock discontinuities, inclination angle, and ...
