A square building (15 m × 15 m in plan) is to be constructed on a site where the soil profile consists of 3m of clay with an over-consolidation ratio that varies from 5 at the surface to 2 at 3m overlying a 5m thick clay layer with an over-consolidation ratio of 2, which overlies rock. The soil properties are Cc = 0.4, Cr = 0.1 and fsat = 18 kN/m3 for both clays, and the water table is 1 m below the soil surface. Determine the settlements when a stress of 60 kPa is applied by the building. To determine the initial void ratio assume Gs = 2.65. Assume also that settlements of any sand and gravel layers can be ignored.
