A soil profile is provided below. The estimated stresses from a spread footing overlying a 9 meter thick over-consolidated clay layer are: 180.0 kPa (top of the clay layer) 97.2 kPa (middle of the clay layer) 64.3 kPa (bottom of the clay layer) Estimate the primary settlement (in meters) of the clay layer assuming Cc'= Cc/log (1+eo) = 0.22 and Cs’ =Cs/log (1+eo)= 0.04 taken from consolidation curves. Assume the pre-consolidation pressure is 215 kPa. Assume no settlement from the overlying sand layer. Depth Yng=(7.3 SAND -3 m YSAT = 19.8 KLA - 12 m
