Data-driven estimation of joint roughness coefficient
Journal of Rock Mechanics and Geotechnical Engineering, 2021 Joint roughness is one of the most important issues in the hydromechanical behavior of rock mass. Therefore, the joint roughness coefficient (JRC) estimation is of paramount importance in geomechanics engineering applications.

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 ...

Determination of joint roughness coefficient (JRC) for slope stability analysis: a case study from the Gold Coast area, Australia [PDF]
Landslides, 2013 Surface roughness of rock discontinuities is an important factor that determines the strength characteristics of rock mass. Joint roughness coefficient (JRC), which is typically measured by means of Barton’s combs in the field, is widely used to describe the joint roughness.

Science and Engineering of Composite Materials, 2021 The joint roughness has an influence on the uniaxial compressive strength (UCS) and characteristic strength of the rock, but the relationship of the influence is yet to be obtained. In this article, the influence of the size of the rock with rough joints
