Current literature on infilled rock joints has also neglected the effect of the degree of saturation of infill on the shear behaviour. In most instances, fully saturated infill has been used or assumed, and the contribution of matric suction on the shear strength of joints having unsaturated ...

In addition to the boundary normal stiffness imposed by the surrounding rock mass, there are other parameters that may affect the shear behaviour of rock joints such as the joint surface roughness and strength, the level of initial normal stress acting on the joint interface, the presence of inf...
However, natural rock joints are 3D in shape and they have rough joint walls and irregular joint apertures, and water flows through the joint void space during shearing (Olsson and Barton, 2001). Therefore, the coupled hydro-mechanical behaviour of rock joints requires a thorough understanding of...
