A flexible rectangular raft foundation, 4 m wide and 5 m long, is to be constructed on the surface of a layer of soft normally consolidated clay, 8 m thick and will support a uniform pressure of 60 kPa. The properties of the clay which are constant thought out the deposit are:
Saturated unit weight of clay: 18.8 kN/m3
Specific Gravity= 2.72
Compression index = 0.12
The water table is at the ground level. The moisture content of the clay decreases linearly from 36% at ground to 28% at the base of the clay layer. Determine the maximum consolidation settlement at the centre of the foundation. Divide the clay layer into two sub-layers for settlement computation.
