Estimate the ultimate consolidation settlement under the centerline of a 17 x 17 m mat foundation. The mat is 1.2 m thick reinforced concrete, and the average stress on the surface of the slab is 80 kPa.The soil profile is shown in Fig. P10.17. Oedometer tests on samples of the clay provide these average values:

σ'ρ = 130 kPa, Cc = 0.40, Cr = 0.03

Neglect any settlements due to the sand layer.
