The following results were obtained from an oedometer test on a specimen of saturated clay: 54 107 214 429 214 107 54 27 Pressure (kPa): 1.024 1.012 1.001 0.994 1.068 1.144 1.217 1.243 Void ratio: A layer of this clay 8 m thick lies below a 4 m depth of sand, the water table being at the surface. The saturated unit weight for both soils =19 kN/m3=19 kN/m3. A 4 m depth of fill, unit weight =21 kN/m3=21 kN/m3, is placed on the sand over an extensive area. Determine the final settlement due to consolidation of the clay. If the fill were to be removed some time after the completion of consolidation, what heave would eventually take place due to swelling of the clay?
