The Influence of Roughness on the UCS of Discontinuous Jointed Rocks
Shock and VibrationJoint roughness and size effect are key factors controlling the uniaxial compressive strength (UCS) of discontinuous jointed rock masses. However, there is currently a lack of a unified quantitative model that can simultaneously characterize the ...

Expression and Analysis of Scale Effect and Anisotropy of Joint Roughness Coefficient Values Using Confidence Neutrosophic Number Cubic Values [PDF]
Neutrosophic Sets and Systems, 2023 : The JRC data collected from a rock mass joint surface difficultly obtain enough large-scale JRC sample data, but small-scale JRC sample data, which usually contain indeterminate and incomplete information due to the limitation of the measurement ...

ASEAN Journal on Science and Technology for Development, 2011 The basic friction angle, Φb for artificially sawn discontinuity planes for fresh granite, as determined by tilt testing, has an average value of 30º. For the natural rough discontinuity surfaces, a wide range of values have been determined for the peak ...

Quantitative study on joint roughness coefficient (JRC) of rock mass
IOP Conference Series: Earth and Environmental Science, 2019 Ten Barton's standard roughness rating profile curves have been digitized by the interpolation approach with MATLAB software. It is proved that the way of digitizing the JRC curves is feasible, based on the contrastive analysis of slope root-mean-square of the JRC curves provided in this article and the others.
