Determine the primary consolidation settlement for the 20 m long pile group shown below. Soil properties by layer are given in the figure, and the clay layers are normally consolidated. Assume a 2:1 load spread starting at a depth of 2/3 of the embedment depth, L. The pile group is square and has dimensions 2.6 m by 2.6 m in plan view. The groundwater table is 1 m below the ground surface. Q = 4000 kN 1 m Sandy soil Y =18.5 kN/m³ Q'=330 V W.T. 7 m .Group.. piles Clay 1 Y =17.2 kN/m³ e,=0.83 C=0.23 Ax B = 2.6 m x L= 20 m 14 m 2.6 m Clay 2 Y =17.5 kN/m³ e,=0.78 C=0.22 8 m Clay 3 Y =18.0 kN/m³ e-0.76 C=0.20 12 m Rock
