This tutorial looks at the Slope Stability probabilistic analysis capabilities based on a published case history (Christian et al. 1994). The probabilistic analysis results from Slope Stability using the Monte Carlo method and 1D spatial variability are demonstrated in this example. The cohesion and friction angle values of the soil layers are used as random variables in this example.
The results of the slope stability analysis are obtained through Ordinary/Fellenius, Bishop Simplified and the Janbu Simplified method. It is assumed in the Slope Stability model that all the probabilistic input variables are normally distributed.
