Slide Tutorials > Overall Slope Reliability
This tutorial demonstrates the Overall Slope probabilistic analysis method in Slide. With this method, the critical surface search is repeated for each sampling of the random variables. This can result in multiple critical slip surfaces being located. The resulting probability of failure is more representative of the entire slope. In comparison, the Global Minimum probabilistic analysis method only performs the probabilistic analysis on a single slip surface (the deterministic Global Minimum slip surface).
