The soil profile at a site consists of 3 m of sand (ym = 17.5 kN/m³, ysat = 18.9 kN/m³) underlain by 6 m of clay (w = 27%, Gs = 2.70, mv = 0.32 MPa ¹, Cx=4.9 mm²/min), which is underlain by bedrock. The water table lies 1 m below the ground level. A 3 m-high compacted fill (ym = 20 kN/m³) is placed on the ground in an attempt to raise the ground level. a. What would be the final consolidation settlement of the clay layer? b. How long will it take for a 50 mm consolidation settlement to occur? c. What would be the consolidation settlement in one year?
