ABSTRACT
The probabilistic analysis of geotechnical structures presenting spatial variability in the soil properties is generally performed using Monte Carlo simulation (MCS) methodology. This method is not suitable for the computation of the failure probabilities encountered in practice (especially when using a computationally expensive finite-element/finite-difference deterministic model) due to the large number of simulations required to calculate a small failure probability. For this reason, only the mean value and the standard deviation of the system response were extensively investigated in literature when using this method.
