A soil profile is provided below. The estimated stresses from a spread footing overlying a 10 meter thick over-consolidated clay layer are: 180.0 kN/sq m (top of the clay layer) 64.3 kN/sq m (bottom of the clay layer) 97.2 kN/sq m (middle of the clay layer) Estimate the primary settlement (in meters) of the clay layer assuming Cc'=Cc/log(1+eo)= 0.44 and Cs' = Cs/log(1+eo)= 0.08 taken from consolidation curves. Assume the pre-consolidation pressure is 160 kPa. Assume no settlement from the overlying sand layer.
