A 5 m thick clay layer lies between two layers of sand each of 3 m thick, the top layer being at ground level. The water table is 1 m below the ground level, but the lower layer of sand is under artesian pressure, the piezometric surface being 2 m above ground level. The saturated unit weight of clay is 20 KN/m² and that of sand is 19 kN/m³, Above the water table, the unit weight of sandy soil 17 kN/m³. Calculate the effective stress just below the clayey layer (in kN/m², up to two decimal places).

A stratified soil is to be analyzed for stresses. The stratified soil is composed of sand, silt, clay and gravel. The 2.80-m thick gravel underlays the 3.60-m thick clay while the 4.0-m thick sand which overlays the 3.0-m thick silt is overlain by the gravel. Ground water table is at a depth of 8.0-m from the surface of the stratified soil. Soils above GWT are dry.
