The soil profile at a site consists of a 2.0 m thick sand layerat the top, underlain by a 3.0 m thick clay layer. The watertable lies at a depth of 1.0 m below the ground level. Thebulk and saturated unit weights of the sand are 16.0 kN/m3and 19.0 kN/m3, respectively. The properties of the clay are:water content = 45.0%, specific gravity of the soil grains =2.70, compression index = 0.65, swelling index = 0.08, andoverconsolidation ratio = 1.5.a. The ground level is raised by placing a 1.5 m high compactedfill with unit weight of 20.0 kN/m3. What is theconsolidation settlement?b. When the consolidation due to the fill is completed,it is proposed to construct a warehouse imposing a uniform pressure of 40.0 kN/m2. What would be theconsolidation settlement due to the construction of thewarehouse?

a. The ground level is raised by placing a 1.5 m high compacted
fill with unit weight of 20.0 kN/m3. What is the
consolidation settlement?
b. When the consolidation due to the fill is completed,
it is proposed to construct a warehouse imposing a uniform pressure of 40.0 kN/m2. What would be the
consolidation settlement due to the construction of the
warehouse?
