Figure 1From: Mechanical and hydraulic behavior of a rock fracture under shear deformationSurface roughness profiles of specimens. (a) Specimens J055, (b) J107, (c) J122, (d) J200. The flow direction length, width, and height were set at 80, 120, and 120 mm, respectively. The fracture surface roughness was measured with a laser displacement sensor with a spot diameter and resolution of 0.1 mm and 4.0 μm, respectively.Back to article page
