A 3 ft square footing carries a sustained load of 10 k. It is placed on the surface of a 30 ft thicksaturated overconsolidated clay underlain by dense sand. Based on laboratory tests, the clay can be adequately modeled using the e@log@p method. The laboratory tests provide the follow-ing compressibility information for the clay: g = 123 lb/ft3Cc1 + e0= 0.06Cr1 + e0= 0.002sm′ = 900 lb/ft2 The groundwater table is located at the ground surface. Compute the settlement of the footing.
