Figure 5
The image illustrates a two-dimensional slope cross-section with distance in metres on the x-axis from 0 to 30 and elevation in metres on the y-axis from 0 to 15. The ground surface is shown as a black polyline with a horizontal upper bench at about 10 metres elevation, a downward sloping face to about 5 metres elevation near 20 metres distance, and a lower horizontal bench extending to about 25 metres distance. A red dashed curved line within the slope depicts the critical deterministic slip surface. An arrow points to this curve with the label Critical deterministic slip surface, F S equals 1.343, indicating the factor of safety associated with the failure surface.Profile of the slope in Example 2
