Abstract
Slope stability analysis is a classical problem of geotechnical engineering characterized by many sources of uncertainty. Some of these sources are connected to the uncertainties of soil properties involved in the analysis. Current practice of slope stability analysis relies in the deterministic characterization and assessment of performance of embankments, excavations and Municipal Solid Waste (MSW) landfills. These slopes have been evaluated in terms of the factor of safety, where the shear strength mobilized along the failure envelop is compared with the shear stresses generated due to self-weight of the soil mass and surcharge loading on the slope. The significant uncertainties associated with the shear strength and shear stresses render deterministic modeling potentially misleading. For example, two slopes with the same factor of safety can have significantly different probabilities of failure.
