...; testing and modeling of rock joints become more and more important (Stephanson & Jing, 1995). Few works have been dedicated to the progressive degradation of the joint surface morphology during shear displacement and its influence on stress-strain-dilatancy. These mechanical parameters characterizing...

... ABSTRACT ABSTRACT: The paper presents findings of an experimental as well as theoretical/analytical research initiated (a) to quantify joint surface roughness on a plane and then (b) to develop a new peak shear strength criterion for rock joints which has the capability of capturing...
