The following figure shows a uniformly distributed load applied at the ground surface. A sample was obtained from the center of the clay layer, and the consolidation test results are shown below.

Given:

Δσ = 2,000 psf

H₁ = 10 ft

H₂ = 10 ft

H₃ = 40 ft

e_o(clay) = 1.25

γ_dry(sand) = 110 lb/ft³

γ_sat(sand) = 115 lb/ft³

γ_sat(clay) = 120 lb/ft³

Consolidation Test Results

a) Determine the compression index, C_c

b) Calculate the primary consolidation settlement for the clay layer
