Quantitative estimation of joint roughness coefficient using statistical parameters
International Journal of Rock Mechanics and Mining Sciences, 2015 where τ is the peak shear strength of the rock joint, σ is the normal stress, JRC is the joint roughness coefficient, JCS is the strength of joint wall, φb is the basic friction angle. Over the last half century, researchers have kept working on techniques for estimating JRC of rock joints for or from this model.

Relationship between joint roughness coefficient and fractal dimension of rock fracture surfaces
International Journal of Rock Mechanics and Mining Sciences, 2015 AbstractNumerous 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 limitations.

The temperature-dependent shear strength of ice-filled joints in rock mass considering the effect of joint roughness, opening and shear rates [PDF]
The Cryosphere, 2023 Global warming causes many rockfall activities in alpine mountains, especially when ice-filled joints in the rock mass become thawed. The warming and thawing of frozen soils and intact rocks have been widely studied in the past several decades; however ...
