A square footing 4 mx 4 m is located at a depth of 1.0 m in a layer of saturated clay 13 m thick, a firm stratum lies immediately below the clay. Characteristic parameters obtained from oedometer and triaxial tests for the clay are as follows: A= 0.42, cu =100 kPa, d=0, c=0, Ø=32°, m, = 0.065m²/MN, 7=21kN/m³, Eu = 300cu. Determine the total settlement under the centre of the footing carrying a net pressure of 200 kPa using Skempton-Bjerrum method.
