1. A smooth unyielding wall retains a dense cohesionless soil with no lateral movements of soil ( at rest condition is assumed). The wall has a height of 2.5 m. The cohesionless soil has a unit weight of 16 kN/m³ and a saturated unit weight of 18.39 kN/m³. Angle of internal friction is 37°. The ground water table is located 1.0 m. below the ground level. smooth unyielding wall 1. Compute the total lateral force acting on the wall. 2.
