Transcribed Image Text: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.
