The soil profile at a site consists of a 3-m thick sand layer (moist unit weight = 16.5 kN/m^3, saturated unit weight = 18.5 kN/m^3) underlain by a 6-m thick clay layer (w = 27%, Gs = 2.70, mv = 0.31 MPa^-1, Cv = 2.6 m^3/year), which is underlain by a gravel layer as shown in the figure. A 3 m compacted fill with a unit weight of 20 kN/m^3 is required to be placed at ground level. a) What would be the final consolidation settlement, in mm rounded to the first decimal place? b) How long will it take for 50 mm consolidation settlement, in months rounded to the first decimal place? c) What would be the consolidation settlement in one year, in mm rounded to nearest whole number?
