Question 3 Figure shows a cantilever sheet-pile wall penetrating a granular soil. Assume, y = 16 kN/m, Ysat 19 kN/m, p = 24, and yw = 10 kN/m. (a) Draw the pressure diagram of the cantilever sheet-pile wall (may not necessarily be on scale). (b) Determine the theoretical depth of embedment. (c) What should be the minimum section modulus of the sheet piles? Use Gall = 165 MN/m. 5m Dredge line sand Ysat c' 0 2 m sand Y 0 sand Ysat . Groundwater table
