Abstract


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 open mine, and also part of the probabilistic method which is an alternative approach in estimating the stability of a slope with a failure probability value (FP). This paper explains the characterization process using the Kolmogorov-Smirnov (K-S) method, which will determine the most appropriate function for the distribution of the random variable. The characterization results can be used in determining the Safety Factor including the level of confidence and probability of Failure based on the best fitting function.
