This Chapter Earth-Pressure--and-Retaining--Walls consists of the following topics

A retaining wall 4m high has a smooth vertical back. The backfill has a horizontal surface in level with the top of the wall. There is a uniformly distributed surcharge load of intensity 36 KN/`m^3` over the backfill. The unit weight of the backfill is 18 KN/`m^3` and angle of shearing resistance is `30^0` and cohesion is zero. Determine the magnitude and point of application of active pressure per metre length of the wall.

In above problem, if water table rises behind wall to an elevation of 1.5 m below top, determine total active pressure and ots point of application. Take submerged weight of sand as 12 KN/`m^3`. Assume that re is no change in angle of shearing resistance due to submergence.

A vertical excavation was made in a clay deposit having weight of 20 KN/`m^3`. It caved in after the depth of digging reached 4m. Taking angle of internal friction to be zero, calculate the value of cohesion. If the same clay is used as a backfill against a retaining wall upto a height of 8m, Calculate:
  • total active earth pressure
  • total passive earth pressure
