An anchored sheet-pile bulkhead is shown in Figure P14.6. Let L1 5 4 m, L2 5 9 m, l1 5 2 m, g 5 17 kN/m3 , gsat 5 19 kN/m3 , and f9 5 348. a. Calculate the theoretical value of the depth of embedment, D. b. Draw the pressure distribution diagram. c. Determine the anchor force per unit length of the wall. Use the free earth-support method.
