Probability study on submarine slope stability

Abstract

Most of the parameters used in slope stability analyses, in particular the mechanical soil properties, are uncertain. Probability theory and reliability analyses can provide a rational framework for dealing with uncertainties. Different methods for doing reliability analysis for slopes are discussed in this study and applied to case studies. The results obtained from FOSM, PEM, and FORM via response surface method combined with the finite element method are compared, and the parameters which contribute most to the uncertainty in the factor of safety are identified.
