INTERVAL ANALYSIS MODEL OF GEOMATERIAL PARAMETERS FOR UNCERTAINTIES IN SLOPE STABILITY ASSESMENT

This paper is based on a comprehensive analysis of geomaterials parameters. It introduces the interval analysis model for stability assesment of slopes. By referring interval mathematics idea, the interval limited equilibrium method is used to derive the interval minimum safety factor of slopes. Based on this foundation, the paper carries out the non-probabilistic reliability analysis of slope stabilities.
