Question 1: A sheet pile wall isolates two flooded areas as shown in Figure 1. The head loss ÿH generates a downward flow on the upstream side and an upward flow on the downstream side. If the saturated soil has a density of 2375 kg/m3 on either side of the curtain, calculate the effective stress at points A and B. 1 m 4 m 5 m 7.5 m 12 = 150 kPa Figure 2 Figure 1- Question 2: Using the data in Figure 2, calculate the vertical stress induced by the loading of the foundations at point A, located 2 m deep, halfway between the two footings. Use the figure 5 to find the coefficient of influence. Representat B 6 m 2 m 3m → 1 m 2 111 311 91 = 125 kPa
