Reliability Analysis of Slope Stability using Monte Carlo Simulation and Comparison with Deterministic Analysis
نویسنده
چکیده
Traditional slope stability analysis is limited to the use of single valued parameters to analyze a slope‟s characteristics. Consequently, traditional analysis methods yield single valued estimates for factor of safety of a slope‟s stability. However, the inherent variability of the soil characteristics which affect slope stability indicates that the stability of a slope is a probabilistic rather than a deterministic situation. In other words, the stability of a slope is a random process which is dependent on the relative distribution of controlling soil parameters. For a natural slope, the stability deciding parameters vary considerably throughout the extent of slope. In this paper, the variability of soil properties and their effect on stability of a natural slope has been studied incorporating the probabilistic analysis using Monte Carlo simulation and deterministic analysis using Geo-Studio and PLAXIS. The factors of safety have been determined using the two approaches and effect of dynamic loading input on slope stability has been studied.

Probabilistic analysis of stability of chain pillars in Tabas coal mine in Iran using Monte Carlo simulation
Performing a probabilistic study rather than a determinist one is a relatively easy way to quantify the uncertainty in an engineering design. Due to the complexity and poor accuracy of the statistical moment methods, the Monte Carlo simulation (MCS) method is wildly used in an engineering design. In this work, an MCS-based reliability analysis was carried out for the stability of the chain pill...
