Slope Stability Analysis Verification - Non-Homogeneous Soil

Non-homogeneous Stratigraphy - Slope Stability Analysis


This example presents a slope stability analyis for a slope with non-homogeneous stratigraphy (three layer slope). The factor of safety and its corresponding critical circular failure surface is required.

Figure 1- Model of the problem








Note :    Referee Factor of Safety = 1.39 [Giam]


Mean Bishop FOS (16 samples) = 1.406


Mean FOS (31 samples) = 1.381
