A tower is to be constructed on a 30m x 30m raft foundation resting on sand at a depth of 6 meters below the ground surface to have a basement. The sand starts from the ground surface and extends for 12 meters below the foundation level followed by an extended rock layer with Emass 0.3 GPa and v = 0.25. The unit weight and Young's Modulus of sand are 20 kN/m³ and 45,000 kN/m², respectively. Calculate the expected settlement of such a raft if the foundation pressure due to the dead and live loads is 400 kN/m2. Is the calculated settlement tolerable? Why?
