Question
An infinite slope of soil, with height 10 m, is
inclined at an angle of 35° to the horizontal.
The soil has c' = 22 kN/m², ' = 22º. A
stability analysis by the method of slices has
given the following forces per running meter
Σ Shearing forces = 350 kN
Σ Normal forces = 755 kN
Σ Neutral forces = 175 kN
If the length of arc is 19 m then the ratio
of F.O.S with respect to cohesion to the
F.O.S with respect to shearing strength is
