A terrain consists (from top to bottom) of 1 meter dry sand (γ = 17 kN/m3 ), 4 meter saturated sand (γ = 20 kN/m3), 2 meter clay (γ = 18 kN/m3 ), 5 meter sand (γ = 20 kN/m3 ), 4 meter clay (γ = 19 kN/m3 ), and finally a thick sand layer. The terrain is loaded by an additional layer of 2 meter dry sand (γ = 17 kN/m3 ). The deformations of the clay layers will be analyzed by performing oedometer tests on samples from each clay layer. What should be the initial load on each of the two samples, and what should be the additional load?
