The author considers the analysis of earth slopes by the application of a limit equilibrium failure method using simplifying assumptions about soil properties. These assumptions are that it is a rigid-plastic material and that its shear strength conforms to Coulomb law. Although a deficiency of such a model is that it applies to a rigid-plastic material, it can be expected to predict failure with reasonable accuracy providing realistic values have been determined for shear strength and pore-water pressure. A failure model appropriate to the analysis of slip surfaces which are non-circular in cross-section would have to consist of elements rather more complex than the simple, vertical slices considered in this analysis. Developments in the analysis of earth slope stability will lie in the application of finite-element and finite-difference methods. /TRRL/
