Simple Slope Example (no pore pressures considered)
This example presents the simple case of a total stress analysis without considering pore water pressures. The soil properties are presented in Table 1 and the model of the problem is shown in Figure 1. The factor of safety and its corresponding critical circular failure is required.
Table 1: Material Properties
c΄ (kN/m2) | φ΄ (deg.) | γ (kN/m3) |
3.0 | 19.6 | 20.0 |
Figure 1 Model of the problem
Method: Bishop | Factor of Safety |
Normal model | 0.978 |
Reversed model | 0.994 |
Note : Referee Factor of Safety = 1.00 [Giam]
Mean Bishop FOS (18 samples) = 0.993
Mean FOS (33 samples) = 0.991
