DEFORMATIONAL MECHANISMS OF A ROCK MASS

A jointed rock mass is represented as an anisotropic composite material on which the theory of pseudo elasticity is applied. The requirement up to this stage is that the mechanisms of slip, rotation, and or material failure do not occur. Deformational modes making up the deformational response of the anisotropic pseudo-elastic rock mass are considered. Anisotrophy by combining joint sets is then examined and the effects of rock bolting introduced. Mechanisms of slip, rotation and or material failure are then superimposed on the deformations of the anisotropic pseudo-elastic rock mass. Stability and instability of the rock mass caused by the formation of hinges due to slip rotation and material failure are discussed. (Author/TRRL)
