e 2. A soil profile consists of 10 m of sand (y 17.6 kN/m3) over 3 m of soft clay (y 17.3 kN/m2, e, = 1.6, C 1.3, = 1.3, C,/C, = 0.2) over gravel. The water table is 3 m below the ground surface and a hydrostatic condition exists throughout the soil profile. Before constructing a structure at the site, the clay layer is preconsolidated by lowering the water table by 3 m and pumping from the gravel layer at such a rate that piezometric head in the gravel drops by 6 m. Compute the settlement resulting from primary consolidation of the clay layer assuming that pumping continues for a long time.
