Slope Stability Example - Simple Slope with Pore Pressures

Slope Stability Example with Pore Pressures


The soil parameters of this problem, the external loadings and the piezometric surface are shown in Tables 1, 1 and 3 respectively. The effect of the tension crack is to be ignored.  The factor of safety and its corresponding critical non-circular failure surface is required.


Table 1: Material Properties







Table 2: External Loading







Table 3: Data for Piezometric surface
















Figure 1- Model of the problem









Note: Referee Factor of Safety = 0.78 [Giam]


Mean Non-circular FOS (20 samples) = 0.808


Referee GLE Factor of Safety = 0.6878 [Slope 2000]
