A 5m thick clay layer lies between two layers of sand each 4m thick, the top upper layer being at ground level. The water table is 2m below the ground level but the lower layer of sand is under artesian pressure, the piezometric head being 4m above ground level. The saturated density of clay is 20kN/m3 and that of sand is 19kN/m3 . Above the water table, unit weight of sand is 16.5kN/m3 . Calculate the effective vertical stress at the top and bottom of the clay layer.

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.
