A stratum of clay1.80 meters thick below an incompressible soil will be subjected to a stress increase of 36 kPa at the center of the layer. The magnitude of the pre-construction soil overburden pressure is 68 kPa at the center of the layer. A laboratory compression tests indicates that the clay is overconsolidated with a preconsolidation pressure equal to 80kPa. The value of the compression index, Cc=0.30 and the swell index is 0.05. The void ratio of the clay is 1.50. Determine the settlement of the clay layer due to this condition.
