Effect of cohesion on stability of fissured rock slopes

Gaziev, E. G. / Rechitski, V. I.

Summary The pattern of failure of fissured rock slopes depends substantially on their interior structure. Sometimes separation and downfall of individual blocks from the slope surface occur, and sometimes this downfall takes the form of an avalanche, depending on the interaction of beds forming the slope. The nature of failure changes sharply with increased cohesion between the rock blocks (when the cohesion reaches its critical value $ C_{*} $) and does not depend on the joint pattern. The sliding rock mass moves as a whole in this case, on a subvertical rupture surface.
