A normally consolidated clay layer experienced a settlement of 10 mm when the effective stress increased from 100 kN/m² to 200 kN/m². What will be the expected settlement if the effective stress is further raised from 200 kN/m² to 400 kN/m²?

Explanation

Since the clay is normally consolidated, settlement is proportional to the change in effective stress. The increase from 100 to 200 kN/m² caused 10 mm settlement, so doubling the stress again from 200 to 400 kN/m² will result in the same 10 mm settlement.
