A series of rock-joint behavior routines which, briefly stated, allow the shear strength and normal stiffness of rock joints to be estimated, graphed, and numerically modelled, for instance, in the computer code UDEC-BB. Coupled behavior with deformation and changes in conductivity is also included (Barton 2016).

A key aspect of the criterion is the quantitative characterization of the joint, joints, or joint sets in question, in order to provide three simple items of input data. These concern the joint-surface roughness (JRC: joint roughness coefficient), the joint-wall compressive strength (JCS: joint compressive strength), and an empirically derived estimate of the residual friction angle (φr). These three parameters have typical ranges of values from: JRC = 0 to 20 (smooth-planar to very rough-undulating), JCS = 10 to 200 MPa (weak-weathered to strong, unweathered) and φr= 20° to 35° (strongly weathered to fresh-unweathered). Each of these parameters can be obtained...
