A strip footing 2.5 m wide carries a uniform pressure of 300 kPa on the surface of a deposit of sand, as shown in the scheme below. The water table is at the surface. The sand has a saturated unit weight = 20 kN/m³. Determine the effective vertical stress at a point 3 m below the centre of the footing before and after the application ofthe pressure. 2.5 m q = 300 kPa V W.T Sand: 3m y=20 kN/m3 Scheme 2.27
