Limit analysis for porous materials applied for slope stability analysis

Slope stability analysis is a classical geotechnical problem. It aims to characterize the potential failure surface and the slope safety factor for a given geometry and loading conditions. From a mechanical point of view the analysis is carried out to check the condition which soil structures failure. Failure condition can be analyzed by analyt- ical, experimental and numerical methods. Griffiths and Lane point out some methods used in the literature as the equilibrium method, modified Bishops method, Morgenstern and Price among others.The objective of this work is to evaluate the slope stability prob- lem, considering the soil as a porous media obeying the yield function proposed by Ulm, Cariou and Gathier.
