Question

Course: Soil mechanics
Theme: Fellenius Method
Determine the stability of a slope and the Critical Height, if the weathered fraction is 35 m and the following effective soil properties were determined. Unit weight 1.32 g / cm3, the angle of friction of 19 °, effective cohesion of 0.35 kg / cm2, the slope of the slope is 23 °

Answer 1

FOS is determined by dividing the resisting force to the destabilizing force. If FOS >1 then slope is stable. Also taking FOS =1 critical height is determined.
