Comparison of Mechanically Determined with Profile-Based Joint Roughness Coefficients

2018
The most popular index for the geometrical characterization of rock discontinuities in rock mechanics is the Joint Roughness Coefficient (JRC). Direct shear tests or mechanical index tests such as tilt- and/or push-tests are most suitable to determine the coefficient.

Natural fracture profiles, fractal dimension and joint roughness coefficients

Rock Mechanics and Rock Engineering, 1994
Thirteen natural rock profiles (Barton and Choubey, 1977) are analyzed for their fractal properties. Most of the profiles were found to approximate fractal curves but some also showed features of specific wavelengths and amplitudes superimposed on fractal characteristics.

Shear behaviors of ‘real’ natural un-matching joints of granite with equivalent joint roughness coefficients

Engineering Geology, 2016
Abstract Contact planes of a natural unfilled rock joint often portray dissimilar roughness characteristics particularly at shallow depth. Some researchers investigated shear strength behaviors of un-matching joints (i.e. joints with dissimilar surface morphologies) through laboratory experiments using mimicked discontinuities.

Fractal-wavelet-fusion-based re-ranking of joint roughness coefficients

2019
Nowadays, Barton’s Joint Roughness Coefficients (JRC) are widely used as the index for roughness and as a challenging fracture property. When JRC ranking is the goal, deriving JRC from different fractal/wavelet procedures can be conflicting. Complexity increases when various rankings outcome from different calculation methods. Therefore, using Barton’s
