1. A smooth, unyielding wall retains loose sand as shown in the figure below. Assume that no lateral movement occurs in the soil mass, and the at-rest condition prevails. Draw the diagram of earth pressure against the wall and find the total lateral force acting on the wall and the location of the force from the base if the groundwater table is located 2 m below the ground surface, as shown in the figure. Smooth Unyielding Wall 2 m tttt ttttttttttt Cohesionless Soil y = 16.50 kN/m $ = 30° 3 m 1 m Groundwater Table
