Abstract : This report is divided into eight sections and an executive summary. Section 3 presents various kinds of uncertainties in slope stability analysis and methods for handling these in the probabilistic slope stability methodology. A description of the model for performing probabilistic slope stability analysis is presented in Section 4 and the field program to develop the necessary probabilistic parameters is described in Section 5. A case study which utilized the methodology is reviewed in Section 6. Section 7 contains evaluations of the methodology by an independent consultant and by the Utah State University development team. Section 8 outlines additional case studies and development work needed to generalize the applicability of the methodology. Finally, the relationship of the methodology to an integrated risk assessment framework which considers all likely causes of slope failure is discussed in Section 9.
