Question:

Figure 12.42 shows a soil profile. The uniformly distributed load on the ground surface is Ds. Given: D_s= 1000 lb/ft²,
H₁ = 8 ft, H₂= 15 ft, and H₃ = 17 ft. Also,
Sand: gdry = 110 lb/ft³, gsat = 115 lb/ft³
Clay: gsat 5 120 lb/ft³, LL = 50, e = 0.9
Estimate the primary consolidation if
a. The clay is normally consolidated
b. The preconsolidation pressure is 2600 lb/ft²
