WebMay 7, 2024 · For a slope of 12 m high and 3V:5H slope, the critical surface passes through the toe of the slope for the clayey and sandy clay soils while for the sandy soil, it passes through the slope as shown in Figs. 6, 7, and 8, respectively. The modes of slope failure for the three types of soils considered changes with the height of the slopes. WebIn general, the greater the uncertainty the higher the required FoS to achieve a minor probability of failure. When seismic slope stability analysis is conducted, the equivalent minimum factor of safety may be reduced to 1.10. An earthquake force is a dynamic load that lasts for a short period hence a lower FoS can be assumed.
