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

Figure 5

Shear stress-shear strain curves and peak shear strengths of simulated specimens. Panels (a-1), (b-1), (c-1), (d-1), and (e-1) are shear stress-shear strain curves of the infilled joints with JRCs of 0–2, 4–6, 8–10, 14–16, and 18–20, respectively. Panels (a-2), (b-2), (c-2), (d-2), and (e-2) are peak shear strengths of the simulated specimens derived from panels (a-1), (b-1), (c-1), (d-1), and (e-1), respectively.
