##### Reference no: EM13210784

A building is to be constructed with a ring beam foundation on a site where the soil profile consists of 2m of clay with an over-consolidation ratio of 4 overlying a 7m thick layer with an over-consolidation ratio of 2, which overlies rock. The soil properties are Cc = 0.3, Cr = 0.08 and gsat = 20 kN/m3 for both clays, and the water table is 1 m below the soil surface. Determine the settlements when a stress of 100 kPa is applied by the building. Determine the differential settlement between the centre line of the ring beam and under the centre of beam. The inner and outer radii of the ring beam are 8m and 12m respectively.
