Three uniformly distributed loads of 100 kPa each are applied to 10 x 10 m square areas on the soil profile shown in Fig. P10.18. Undisturbed samples of the clay were taken prior to construction, and consolidation tests indicated that the average preconsolidation stress is about 110 kPa, the average compression index is 0.50, and the average recompression index is 0.02. Estimate the total consolidation settlement for the clay layer only under the center of the middle loaded area.
