Abstract:
The laboratory shear tests on Apache Leap tuff have been conducted to investigate the joint dilatant behavior and the influence of surface roughness, sample size, water and shear velocity on joint shear behavior, and to compare the fit between Coulomb's linear and Archard's non-linear model. Experimental results indicate that the dilation of rock joint is influenced by joint surface roughness and normal stress. Surface roughness also determines joint shear strength. Sample scale influences the following joint properties, e.g. peak shear strength, peak dilation angle, peak shear displacement and mode of shear failure. This effect depends on normal stress. The shear strength of rock joint also varies with the presence of water and shear velocity. Archard's power law generally gives a better fit on the experimental data than does Coulomb's linear law.
