Abstract
Most rock masses at the earth's surface are divided into homogeneous blocks of rock substance by geological discontinuities of various types. The strength of the rock mass is controlled by the frictional properties of the discontinuities and their orientation. The same factors control movement in rock slopes. These can be divided into falls, topples and slides. Slides are the commonest form of rock slope failure. Large volume slides on planar rupture surfaces should theoretically involve slide masses with high cohesion along discontinuities dipping at angles slightly exceeding the peak angle of friction on the discontinuity. The dynamics of the centre of gravity of the sliding mass can be predicted from energy considerations. Problems exist in the prediction of cohesion along potential rupture planes and in the reach of slides. Falls and topples have received little attention from engineers.
