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).
Enter numerical value using the virtual keypad. Round off where necessary.
