A square footing 4 m × 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, , u 0 c' 0, ' 32, 0.065 / , 2 mv m MN 3 sat 21kN / m , Eu = 300cu. Determine the total settlement under the centre of the footing carrying a net pressure of 200 kPa using Skempton-Bjerrum method.

A square footing 1.5m X 1.5m is located at a depth of 1.0m. The
soil has the following properties: γ = 17.5kN/m3, c= 20kN/m2 and Φ
= 34o. The footing base and ground are horizontal. if the
horizontal component of the weight = 20kN acting at the height of
4m parallel to the side of footing, and vertical component is
500kN, determine ultimate bearing capacity and factor of safety.
