A stability analysis of slopes based on a translational mechanism of failure is presented. The collapse mechanism is assumed to be in the form of rigid blocks analogous to slices in traditional slice methods. The proposed analysis, although based on the kinematical approach of limit analysis, always satisfies the equilibrium of forces acting on all blocks(More)
The widely used Jaky coefficient of earth pressure at rest, K0, is revisited. It is demonstrated that this coefficient was derived from an analysis of the stress state in a sand prism that yields an unrealistic stress field. It is also surprising that the at rest stress state is represented as a function of the limit state parameter internal friction angle(More)
While computational tools have made most graphical methods and charts obsolete, stability charts for slopes are still routinely used in practice. The charts presented here are based on the kinematic approach of limit analysis that leads to a strict lower bound on stability number c/gH or an upper bound on the safety factor. An earlier suggestion is employed(More)
