A compressible 6 m thick clay layer has initial void ratio of 1.70. If final void ratio after construction of building is expected to be 1.61, then what is the coefficient of volume compressibility of soil layer? Assume that during settlement, 150 kN/m^2 increment in stress is observed.
A horizontal stratified soil deposit consists of three layers each uniform in itself. The permeabilities of these layers are 8 × 10–4 cm/s, 52 × 10–4 cm/s, and 6 × 10–4 cm/s, and their thickness are 7, 3 and 10 m respectively. Find the effective average permeability of the deposit in the horizontal and vertical direction (mm/s).

PROBLEM 50: Compute the compression index of undisturbed clay having a plastic limit of 32% and a plasticity index of 8%
The top 500m of a site consists of a clayey sand with a void ratio of 0.90 and a water content of 20.0%. The specific gravity of the soil grains is 2.68. When the ground is compacted at the same water content, there is 45mm reduction in the thickness of this layer. Determine the new void ratio and the unit weight of the soil. I keep seeing answers with 0.5m or 500mm instead of 500m as depth. The question specifically says 500m as the depth and it compressed 45mm when compacted.
