Introduction

SLOPE/W can be used to model the stability of rock slopes using various strength models such as the Barton and Choubey (1977) and Miller (1988) for rock joints or the anisotropic function to model rock mass with linearly anisotropic strength. Linear anisotropy refers to the Mohr-Coulomb criterion with the coefficient of friction and cohesion varying linearly from bedding to cross-bedding direction.

This example demonstrates how a shear-normal function can be used to accommodate the rock joint strength models along with the Hoek-Brown model. The Anisotropic Function material model is also highlighted.
