A 2-meter clay layer (e = 0.88, Gs = 2.67, Cc = 0.305) is overlain with 4-meter-thick sand layer (e = 0.82, G = 2.72). The water table is at the interface of the sand and clay layer. If a 2-meter-thick land fill (γ = 17.97 kN/m3) is placed over the existing ground surface, compute the consolidation settlement (in mm.) of the clay layer. Hint: Use the land fill's resulting pressure on the ground surface as the stress increase. Round off to two decimal places. Selected Answer: 60.25
