A retaining wall 8 m high supports a cohesionless soil having a dry density of 1600 kg/m³, angle of shearing resistance is 33° and void ratio of 0.68. 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 cohesionless soil. a. Determine the nearest value to the total earth thrust on the wall in kN per linear meter if the soil is dry. b. Determine the nearest value of the thrust on the wall in kN per linear meter if owing to inadequate drainage, it is waterlogged to a level 3.5 m below the surface. c. Determine the nearest value to the height above the base of the wall where the thrust acts during the waterlogged condition.

Transcribed Image Text:SIT Z. A retaining wall 8 m high supports a cohesionless soil having a dry density of 1600
kg/m³, angle of shearing resistance is 33° and void ratio of 0.68. 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 cohesionless soil.
a. Determine the nearest value to the total earth thrust on the wall in kN per linear
meter if the soil is dry.
b. Determine the nearest value of the thrust on the wall in kN per linear meter if
owing to inadequate drainage, it is waterlogged to a level 3.5 m below the
surface.
c. Determine the nearest value to the height above the base of the wall where the
thrust acts during the waterlogged condition.
