Abstract. Uncertainties of factors that influence slope stability have been acknowledged by many geotechnical engineers, and these are drawn from the characterization of the geotechnical parameters of the slope. The characterization is associated with a process of identifying the distribution of random variable values used in the design of a single slope of an …
