The effects of discontinuity surface roughness on the shear strength of weathered granite joints
, 2014 Surface roughness is one of the most important parameters governing the shear strength of rock discontinuities. Roughness types may vary based on genesis, physico-mechanical, and mineralogical properties of rocks.

, 2013 Joint roughness coefficient (JRC) is one of the important parameters to determine shear strength of joints. JRC values are generally measured using profile gauges and estimated by comparing the surface profiles with typical roughness profiles. Therefore,

Comparative tests of joint surface roughness of rocks from the McMurdo Sound area, Antarctica [PDF]
, 2019 Barton and co-workers (Barton, 1973, 1976; Barton and Choubey, 1977; Barton and Bandis, 1980; Bandis et al., 1981) have developed an empirical relationship to estimate the peak frictional resistance of a joint, which considers both the joint wall ...

Relationship between joint roughness coefficient and fractal dimension of rock fracture surfaces
, 2015 Numerous empirical equations have been proposed to estimate the joint roughness coefficient (JRC) of a rock fracture based on its fractal dimension (D). A detailed review is made on these various methods, along with a discussion about their usability and

Correlation of joint roughness coefficient and permeability of a fracture
, 2019 This paper uses a new modeling approach to study fluid transport in an open fracture, which relies on data derived from scanned surfaces of fractures and considers surface variations and velocity Laplacians in two orthogonal directions and the bulk flow ...
