Refer to Fig. 10.15, where a 6-m-high vertical wall retains an elastic soil mass. If a strip load applies a uniform pressure at the ground level such that a = 3 m, b = 2 m, H = 6 m, q = 50 kN/m2 , plot the variation of lateral earth pressure on the wall with depth. Find the magnitude and depth for the maximum value of σ′h .
