Li, AJ & Merifield, RS 2007, 'Rock Slope Stability Assessment Based on Limit Analysis', in Y Potvin (ed.),

Predicting the stability of rock slopes presents a significant challenge for geotechnical engineers and plays an important role when designing engineering structures such as tunnels and bridges. This arises due to the difficulty in evaluating the jointed rock mass strength, because rock masses are inhomogeneous, discontinuous media composed of rock material and naturally occurring discontinuities such as joints, fractures and bedding planes. In view of these rock mass characteristics, the simple theoretical solutions based on limit equilibrium methods (LEM) are very difficult to apply. In this paper, numerical finite element limit analysis has been used to evaluate the stability of a rock slope whose strength can be described by the generalised Hoek-Brown failure criterion. A range of stability charts for rock slopes will be presented in which seismic effects will also be incorporated by assuming a pseudo-static body force.
