Q2: A rectangular foundation 4 x2 m, carrying a uniform pressure of 200 kN/m, is located at a depth of 1.5m in a layer of saturated clay 5m thick for which the value of E, is 45MN/m². The layer is underlain by a second saturated clay layer 10m thick for which the value of E, is 80MN/m². A hard stratum lies below the second layer. Ground water table is at the depth of foundation. Determine the average immediate settlement under the foundation.
