A retaining wall 6 m high supports a cohesionless soil having a
dry density of 1650 kg/cu.m., angle of shearing resistance is 31
degrees and a void ration of 0.62. The surface of the soil is
horizontal and level with the top of the wall. Neglect wall
friction and use Rankine’s formula for active pressure of a
cohesionless soil.
1. Determine the total earth thrust on the wall in kN per linear
meter if the soil is dry.
2. Determine the earth thrust on the wall in kN per linear meter
if owing to in adequate drainage, it is waterlogged to a level 3.5
m below the surface.
3. Determine the height above the base of the wall where the
thrust acts during the waterlogged condition.
