Numerical modeling of probabilistic slope stability analysis on Geostudio

Abstract

    Assessing the stability of slopes by limit equilibrium analysis methods have been applied commonly to solve geotechnical engineering problems. Nevertheless, regarding slope stability analysis, there are many random factors. The aim of this paper is to numerically simulate of the slope stability by using the GeoStudio software (Slope/w). The Factors of Safe (FOS) determined by the limit equilibrium following the Morgenstern-Price method combination with Mohr-Coulomb soil properties. The effects of pore-water pressure, cohesion, internal friction angle, unit weight of soil and surcharge loading on slope stability were investigated through a prime instance, take into consideration the random variables with Monte Carlo simulations. The result demonstrates that the FOS of slope depends on random factors and if reliability is increases then the range of FOS is lager. In addition, the change of water level and surcharge should also be taken into account.
