A net contact pressure equals 160 kN/m2 is applied to a stiff clay layer 15 m thick. The footing is 6 m square founded at 2 m depth below ground surface. A layer of silty sand, 2 m thick, overlies the clay and a firm stratum lies immediately below the clay. Oedometer tests on specimens of the clay gave the value of mv =0 13 m2/MN, and triaxial tests gave the value of pore pressure parameter A = 0 35. The undrained Young’s modulus for the clay Eu was estimated equal 55 MN/m2. Determine the total settlement under the footing centre.
