Q10.A 6 m high retaining wall having a smooth vertical back face retains a layered horizontal backfill.
Top 3 m thick layer of the backfill is sand having an angle of internal friction, φ = 30° while the
bottom layer is 3 m thick clay with cohesion, c = 20 kPa. Assume unit weight for both sand and
clay as 18 kN/m3. The totalactive earth pressure per unit length of the wall (in kN/m) is:
