Question

A 3.75m clay layer in the field (drained on one side) is normally consolidated. When the pressure is increased from 50 kPa to 150 kPa, the void ratio decreases from 0.9 to 0.75. The coefficient of permeability of the clay was 6 x 10^-7 cm/s.
• How long (days) will it take to reach 50% consolidation?
• What is the settlement when the soil reaches 50% consolidation?

Final answer should be in 3 decimal places.
