Consider the soil profile shown in figure subjected to the uniformly distributed load, Delta sigma = 950 lb/ft^2, on the ground surface. Given: H_1 = 6 ft; H_2 =16 ft; and H_3 = 18ft. Soil characteristics are as follows: Sand: gamma_d = 114 Ib/ft^3, gamma_sat = 118 Ib/ft^3 Clay: gamma_sat = 117 Ib/ft^3; C_c = 0.24; e = 0.69; C_s = C_c/5 Estimate the primary' consolidation settlement in the clay if The clay is normally consolidated The preconsolidation pressure sigma'_c = 2300 Ib/ft^2
