Research Topic

Shear strength of degradable rock joints

Research Abstract

This study demonstrates the effects of asperity degradation and gouge material distribution on shear behaviour of rock joints based on three dimensional characterizations of the rock joint samples and large scale constant normal stiffness direct shear tests under varies level of normal load and surfaces roughness.
