Feb 1, 2015 · Abstract Monte Carlo simulation (MCS) provides a conceptually simple and robust method to evaluate the system reliability of slope stability, particularly in spatially variable soils. Reliability analysis is operationally decoupled from deterministic slope stability analysis and implemented using a A factor of safety greater than 1. A. The effect of Apr 9, 2022 · The FOS of the soil slope is determined using limit equilibrium based ordinary method of slices [29]. Computers & Geosciences. Dec 1, 2008 · A spreadsheet procedure has been developed for facilitating the proposed solution for the analysis of toppling stability of rock slopes. Samtani, N. . The slope profile in the Excel spreadsheet can be set from cell C13 to cell AZ44, and the soil properties can be set from cell C50 to cell E79. 199-208. When seismic slope stability analysis is conducted, the equivalent minimum factor of safety may be reduced to 1. Slide is the most comprehensive slope stability analysis software available, complete with finite Slope Stability Analysis Spreadsheet Download Link. However, it suffers from a lack of efficiency at small probability levels, which are of great interest in geotechnical design practice. 60 14. MCS method provides a robust and conceptually simple way to estimate the “reliability index” b or slope failure probability P f (e. Jul 19, 2022 · When studying the stability of a slope, the first issue that needs to be clarified is the slip surface, which determines the minimum safety factor. example, probabilistic slope stability analysis. The powerful optimization tool of Excel is employed to obtain the factor of safety of the slope. Besides, the influence of groundwater and stabilizations from the lowermost block of the slope have been overlooked in the available literature Jun 1, 2018 · Amini et al. SLOPE STABILITY 1.
