weakness, present particular difficulties in the assessment of pit slope stability. Various numerical modelling
techniques are available that explicitly simulate the joints and discontinuities within an anisotropic rock
mass. However, due to the computational intensity of these numerical techniques, it is not practical to
explicitly simulate the joint fabric of an entire three-dimensional pit slope for routine stability assessment. In
order to simulate the effects of anisotropic rock mass strength and deformation behaviour on pit slope
stability, a modelling methodology has been developed to account for rock mass anisotropy and scale
effects using a continuum based ubiquitous joint constitutive model. This paper outlines the anisotropic

technique.
