A 10m high gravity retaining wall is required to support a hard clay backfill having a level surface with a unit weight of 17 kN/m^3. Cohesion of hard clay is 45 kN/m^2. Compute (1) the total lateral force resulting from the retained soil for the theoretical active pressure condition (assume Ka = 1.0 for a hard clay backfill), (2) total lateral force resulting from the retained soil for the modified active pressure distribution recommended for a short-term design, (3) total lateral force resulting from the retained soil for the pressure distribution recommended for permanent retaining wall design (assume Ko = 0.90 for a hard clay fill).
