A limit equilibrium method for progressive failure analysis of slopes is proposed based on a technique of non-vertical slices . The local factors of safety are calculated by defining variable factor of safety instead of conventional single value factor of ...

By merging elasto-plastic finite element analysis with random field theory, an investigation has been performed into the stability of an undrained clay slope with spatially varying shear strength. The results of the study lead to a direct comparison between ...

A new three-dimensional (3D) slope stability analysis method is developed based on two-directional moment equilibrium. This method calculates not only the safety factor but also the possible direction of sliding for semispherical and composite failure surfaces. ...

The paper discusses alternative approaches to stability analyses including the traditional deterministic principle, the so-called partial factor principle and the probabilistic approach which assesses the probability of failure rather than the factor of safety ...

This paper reviews the development of finite element slope stability analyses and proposes that such a method can form a practical procedure for solving slope stability problems. Several slope stability methods have been proposed that make use of the finite ...

Some of the methods of slices satisfying moment equilibrium derived for circular slip surfaces have been extended to accommodate noncircular (or composite) type slip surfaces. A question arises regarding the point about which moment equilibrium should be taken ...

Two methods for incorporating the effects of negative pore water pressures into the slope stability analysis are proposed in this paper. the derivation of equations for the factor of safety with respect to force and moment equilibriums are presented. Several ...

Evaluation of limit equilibrium methods with emphasis on factor of safety calculation, slip surface, interslice force function.
