A stratum of clay 1.8 m thick below an incompressible soil will be subjected to a stress increase of 36 kPa. The magnitude of the preconstruction soil overburden pressure in laboratory compression tests indicates that the clay is overconsolidated with a preconsolidation pressure equal to 72 kPa. The value of the compression index Cc= 0.30 and the swell index is equal to 0.05, void ratio of the clay is 1.50.
Determine the change in thickness in the clay layer due to this condition.
