A new approach for quantifying the two-dimensional joint roughness coefficient (JRC) of rock joints

Environmental Earth Sciences, 2021
The joint roughness coefficient (JRC) is the key factor in predicting the peak shear strength of a rock joint. In this paper, we present a new approach for quantitatively calculating the JRC of two-dimensional rock joints. First, the two dimensionless indexes of cumulative relative relief amplitude (CRRA) and weighted average gradient (WAG) are defined

3DEC Simulations of Dynamic Direct Shear Tests Considering Joint Roughness Coefficient (JRC)

57th U.S. Rock Mechanics/Geomechanics Symposium, 2023
ABSTRACT In general, the dynamic properties, e.g., dynamic rock modulus and dynamic rock (shear or tensile) strength are two to three times greater than static moduli and strengths. Thus, understanding the dynamic rock characteristics is necessary to improve the design of support systems in underground mines, nearly

Development of a new equation for joint roughness coefficient (JRC) with fractal dimension: a case study of Bakhtiary Dam site in Iran

Arabian Journal of Geosciences, 2013
The joint roughness has a significant effect on the shear behavior of rough joints, which control the shear strength of jointed rock mass. This index plays an important role in the mechanical and hydraulic properties of rock masses. There have been extensive studies in last a few decades.

Correlation between Joint Roughness Coefficient (JRC) and statistical roughness parameters

Engineering Geology and Geotechnics: Building for the Future, Proceedings of the Conference EUROENGEO 2024
Rocks 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.
