Assume that the clay layer is preconsolidated, o=128 kN/m2, and Cs= 1/5Cc. Estimate the consolidation settlement. Problem 1 Refer to the soil profile shown in Figure 1. Determine the total stress, pore water pressure, and effective stress at A, B, C, and D 3m 1.5 m 5 m Dry sand; e = 0.55 G,= 2.66, Water table Sand G,= 2.66 e=0.48 Clay w= 34.78% G,= 2.74 D Rock 2.13 For a normally consolidated clay layer, given: Thickness = 3.7 m Void ratio = 0.82 Liquid limit = 42 Average effective stress on the clay layer = 110 kN/m2 How much consolidation settlement would the clay undergo if the average effective stress on the clay layer is increased to 155 kN/m2 as the result of the construction of a foundation?
