This paper presents a joint constitutive model that represents the shear behaviour of a large-scale opened rock joint. Evaluation of the degree of opening is made by considering the ratio between the joint wall aperture and the joint amplitude. Scale dependence of the surfa...

The common method for determination of the mechanical properties of the rock joints is the direct shear test. This paper aims to study the effect of boundary condition on the results of direct shear tests. Experimental studies undertaken in this research showed that the peak shear strength is mos...

In developing a shear strength model for rock joints, it is essential to understand the shear behaviour of idealised elastic asperities. In this paper, the shear behaviour of regular triangular elastic asperities subjected to constant normal stiffness (CNS) boundary conditions is examined for a range...
