A rectangular footing (4.55 x 4.8 m.) is placed 1.42 m. below the ground surface. The soil arrangement is composed of sand (ground) for the first 5.55 meters and followed by clay for the next 5.98 meters. The force acting on the footing is 10,647 kN. Determine the settlement of the consolidating layer in mm. Assume a 2V:1H pressure diagram. Unit weight of sand = 16.7 kN/m3. Clay has the following properties: unit weight = 18.9 kN/m^3, void ratio=30, liquid limit = 43
