A 1.5 m square 0.4 thick footing supports a column load of 350 kN. The underlying soil has a unit weight of 18 kN/m3 and the ground water table is 2 m below the ground surface. Compute the change is vertical stress and final vertical stress beneath the corner of this footing at a depth of 5 m using the 2:1 and Boussinesq methods. The footing is placed on the ground surface. Include selfweight of the footing. Discuss the differences in the results.
