Probabilistic Analyses of Slopes: A State of the Art Review

Slope stability analyses are evolving from deterministic analyses, which rely only on the mean value of each parameter, to more advanced probabilistic methods. Moreover, many researchers have shown the benefits of considering spatial variability of soil properties in probabilistic analyses of slopes that may lead to a more economical and/or safer design. Spatial variability is usually modeled by random fields theory in both limit equilibrium and finite element based probabilistic analyses. This paper presents a state of the art review of the literatures on probabilistic analyses of slopes that may help researchers to choose a suitable probabilistic method for their problems.
