Numerical Simulation of Shear Behavior and Permeability Evolution of Rock Joints with Variable Roughness and Infilling Thickness

Figure 4

Typical infill distributions of the simulated specimens. (a-1)–(a-3) Specimens with an equal JRC of 0–2 and infill thickness ratios (t/h) of 0.02, 0.1, and 0.2, respectively. (b-1)–(b-3) Specimens with an equal JRC of 8–10 and t/h of 0.02, 0.1, and 0.2, respectively. (c-1)–(c-3) Specimens with an equal JRC of 18–20 and t/h of 0.02, 0.1 and 0.2, respectively.
