The water content and the total density in a partially saturated sand ( G= 2.64) layer are w=20% and p=1.8 g/cm3 , respectively. If the maximum and minimum values of the void ratio are 0.92 and 0.62, respectively determine the relative density Dr of the sand in this layer.
A stratum of normally consolidated clay 7 m thick is located at a depth 12m below ground level. The natural moisture content of the clay is 40.5 per cent and its liquid limit is 48 per cent. The specific gravity of the solid particles is 2.76. The water table is located at a depth 5 m below ground surface. The soil is sand above the clay stratum. The submerged unit weight of the sand is 1 1 kN/m3 and the same weighs 18 kN/m3 above the water table. The average increase in pressure at the center of the clay stratum is 120 kN/m2 due to the weight of a building that will be constructed on the sand above the clay stratum. Estimate the expected settlement of the structure in cm. a. 9.55 b. 4.96 c. 4.83 d. 23.3
The soil profile at a site consists of 2 m of sand at the groundlevel, underlain by 6 m of clay, followed by a very stiff claystratum that can be assumed to be impervious and incompressible.The water table is at 1.5 m below the ground level. Themoist and saturated unit weights of the sand are 17.0 kN/m3and 18.5 kN/m3, respectively. The clay has an initial void ratioof 0.810, saturated unit weight of 19.0 kN/m3, and coefficientof consolidation of 0.0014 cm2/s.a. When the ground is surcharged with 3 m high compactedfill with moist unit weight of 19.0 kN/m3, the settlementwas 160 mm in the first year. What would be the consolidationsettlement in the first two years?b. If the clay is normally consolidated, what is the compressionindex of the clay?
