Question
A 10 m thkck clay layer is resting over a 3 m thick sand layer and is submerged. A fill of 2 m thick sand with unit weight of 20 kN/m3 is placed above the clay layer to accelerate the rate of consoldiation of the clay layar. Coefficient of consolidation of clay is 9 x 10-2 m3/year and coefficient of volume compressibility of clay is 2.2 x 10 m?/kN. Assume Taylor's relations between time factor and average degree of consolidation. Water table V 10 m Clay 3 m Sand Impervious stratum The settlement (in mm, round off to two decimal places) of the clay layer, 10 years after the construction of the fill, is
