6. (a) During a civil engineering construction work, it is planned to cut a 70? slope, 12m high, measured vertically in soil having a unit weight of 19.5kN/m3, with an effective cohesion of 38.4kN/m2 and an effective angle of friction of 15?. Neglecting all possibility of seepage through the embankment, determine the factor of safety with respect to cohesion. (b) When will failure occur in a slope formed in a cohesionless soil and a cohesive soil?
