A square footing of length 11 m is proposed as a foundation for a building. It is to be built on the surface of a deep layer of stiff clay. The foundation is estimated to carry a uniformly distributed load of 150 kN/m2. Undrained Young's modulus may be assumed to be constant with depth and equal to 16,500 kN/m2 and the effective Poisson's ratio is 0.3. Point F is on the clay surface and is shown 11m 5.5m F 11m 3m (a) Calculate the increase in vertical stress due to this surcharge at 8 m below Point F. (b) Calculate the immediate and total settlement at Point F.
