The shear mechanical properties of rocks with variable angle joints.

ABSTRACT: Variable angle structural surfaces are more common in slopes. However, variable-angle joints have still been approximated as single-angle straight joint planes for analysis in previous studies, which failed to comprehensively capture the mechanical properties of such surfaces. In this paper, joint specimens with variable angles were fabricated using concrete. Direct shear tests were carried out under different normal stress conditions, and the strength, deformation, and failure characteristics of the specimens were analyzed. The results revealed a significant positive correlation between the peak shear strength and shear stiffness of the variable angle specimens with the normal stress, while the correlation between the residual shear strength and the normal stress was relatively insignific
