Consider the sketch of a foundation at a depth of 5m in clay soil with properties below. P is applied eccentrically on the footing. c' = 5kPa, cu = 45kPa, p= 30 You = 18.5kN/m and Yat=21.5kN/m Note, the force is not acting on the centre of the footing, it acts on point P (0.2m from the centreline y-y', and 0.4m from the centreline x-x') 3m 2m CX 4m DV 2.1 2,2 2.3 0.2m 2.5m 2.5m 5m Calculate the ultimate load (P) when the water table is at point B for drained clay. Assume a factor of safety of 2. (15) If the vertical load, P = 310kN/m, calculate the factor of safety for undrained clay when the water table is at point A. (11) Calculate the ultimate bearing when the water table is at point A, C and D for drained clay. (3x3 = 9)
