A load of 1863 kN is carried on a 1.5 by 2 m rectangular foundation at a shallow depth in a soil mass. Determine the vertical stress at the centre of the footing 4 m below the footing underside assuming: (a) the load is uniformly distributed over the pad and, (b) the load acts as a point load at the centre of the foundation.
A pole is held vertically on a soil surface by three equally spaced wires tied to the top of the pole. Each wire has an overall tension of 1 kN and is inclined at 45' to the vertical. Calculate the increase in vertical stress at a depth 1 m below the ground surface beneath the pole. Use Boussinesq's point load theory. 2.

Refer to the cross-section profile through a soil stratum with a point load (P) acting on the surface. Points A & B are at the same depth, similarly points C&D are at the same depth. Horizontal & vertical distances are plotted on the same scale.Using the understanding of variation of incremental vertical stress induced by a point load on the surface, compare the values of incremental vertical stresses at points...
A 5m wide and 10m long rectangular foundation is built on a site where the soil profile consists of 3m of gravel and 4m of clay overlying rigid impermeable rock as shown in Fiqure 8. The foundation carries a surcharge loading of q-65 kN/m2 Initially the water table is 1 m below the surface of the gravel. The water table rises to the surface of the gravel slowly over a period of time and the surface loading induces an increase...
