A retaining wall 7 m high supports a cohesionless soil having a dry density of 1600 kg/m3, the 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 a cohesionless soil. Determine the nearest value of the total earth thrust on the wall in kN per lineal meter if the soil is dry. Determine the nearest value to the thrust on the wall in kN per lineal meter if owing to inadequate drainage, it is water logged to a level 3 m below the surface. Determine the nearest value to the height above the base of the wall where the thrust
