Abstract

Non-circular Random Limit Equilibrium Method (RLEM) uses a combination of non-circular limit equilibrium method, 2D random field theory, and Monte Carlo simulation. Non-circular RLEM has the ability to seek out the weakest failure path in a slope stability analysis using optimization techniques such as Surface Altering, while considering spatial variability of soil properties. This study is a probabilistic analysis of the stability of the Sugar Creek embankment fill slope using non-circular RLEM. This example has been investigated in the literature with other probabilistic methods such as the non-circular limit equilibrium method together with 1D spatial variability analysis. The results of this study show that the values of probability of failure are in good agreement for the 1D and 2D spatial variability cases, while the mean factor of safety values for 2D spatial variability tend to be higher with smaller standard deviations of factor of safety.
