Question

(a) An embankment is inclined at an angle of $35^\circ$ and its height is $15\text{ m}$. The angle of shearing resistance is $15^\circ$ and the cohesion intercept is $200\text{ kN/m}^2$. The unit weight of soil is $18.0\text{ kN/m}^3$. If Taylor's stability number is $0.06$, find the factor of safety with respect to cohesion.

(b) Explain the method of slices for stability analysis of slopes. How can steady seepage be accounted for in this method ?
