A layer of this clay 2.5 m thick lies below a 10 m depth of sand, the water table being at the surface. The saturated weight for both soils is 19 kN/m³. A 10-m depth of fill of unit weight of 21 kN/m³ is placed on the sand over an extensive area. If the fill was to be removed some time after the completion of consolidation, what heave (mm) would eventually take place due to swelling of the clay? (0 d.p). Use unit weight of water of 9.8 kN/m3. Use log base 10.
Soil borings made at a site indicate that the top 8 m is a loose sand, with the groundwater table at 4 m below the ground surface. Below this is a fairly soft blue-gray silty clay with an average water content of 30%. The boring was terminated at 20 m below the ground surface when fairly stiff silty clay was encountered. For the upper sand gammadry = 14.0 kN/m3 and gammasat = 15.0 kN/m3 , where gamma is the unit weight. For the clay, ps = 2.70 Mg/m3 where p is density.
