A Semiempirical Approach to Modeling Shear Strength in Unsaturated Infilled Rock Fractures

Abstract

Abstract This study introduces a semiempirical model characterizing the shear behavior of infilled rock fractures, accounting for both the roughness of rock fracture walls and the presence of unsaturated fine-grained infill materials. The model expands ... Practical Applications Understanding how changes in water content affect the strength of infill materials within rock fractures is critical for the safe design, construction, and long-term stability of slopes, tunnels, foundations, and other rock ...
