An investigation on the correlation between the joint roughness coefficient (JRC) and joint roughness parameters

Construction and Building Materials, 2020
Abstract Correlation of the joint roughness coefficient (JRC) and various parameters for joint roughness evaluation was investigated in this study. A high-resolution 3D laser scanner was employed to precisely record roughness characteristics of 16 tensile fractured rock joints with different sizes.

Estimation of the joint roughness coefficient (JRC) of rock joints by vector similarity measures

Bulletin of Engineering Geology and the Environment, 2017
Accurate determination of joint roughness coefficient (JRC) of rock joints is essential for evaluating the influence of surface roughness on the shear behavior of rock joints. The JRC values of rock joints are typically measured by visual comparison against Barton’s standard JRC profiles. However, its accuracy is strongly affected by personal bias.

A new index to describe joint roughness coefficient (JRC) under cyclic shear

Engineering Geology, 2016
Abstract Rock joint roughness coefficient (JRC) is an important parameter to determine the shear strength of unfilled hard rock joints. It is of great significance to acquire a representative value of JRC. For irregular undulated joints, the JRC has a strong directivity and surface inclination can reflect the roughness difference under the condition ...

Technical Note Estimation of the Joint Roughness Coefficient (JRC) by Visual Comparison

Rock Mechanics and Rock Engineering, 2002
The Joint Roughness Coefficient (JCR) is probably the most commonly-used measure of roughness of rock joint surfaces in current use, and forms an important part of the Barton-Bandis rock joint shear strength criterion. The normal method of evaluating the JCR of a joint is by visual comparison of measured profiles against a set of standard JCR profiles ...
