The effective stress immediately after the fill is placed:
To determine the effective stress immediately after the fill is placed, we need to consider the increase in vertical stress due to the weight of the fill. The unit weight of the fill is given as 20 kN/m3, and the height of the fill is 3 m.
- Calculate the increase in vertical stress:
The increase in vertical stress is equal to the unit weight of the fill multiplied by the height of the fill.
Increase in vertical stress = unit weight × height
Increase in vertical stress = 20 kN/m3 × 3 m = 60 kPa
- Calculate the effective stress immediately after the fill is placed:
The effective stress immediately after the fill is placed is equal to the initial effective stress plus the increase in vertical stress.
Effective stress immediately after fill = initial effective stress + increase in vertical stress
Effective stress immediately after fill = 200 kPa + 60 kPa = 260 kPa
Therefore, the value of effective stress immediately after the fill is placed is 260 kPa.
The effective stress after consolidation settlement is completed:
Consolidation settlement occurs when excess pore water pressure dissipates and the soil particles rearrange themselves under the applied load. This process typically takes some time to complete. Once consolidation settlement is completed, the effective stress will change again.
- The value of effective stress after consolidation settlement is completed will depend on the settlement characteristics of the clay deposit. If the clay is highly compressible, it will undergo significant settlement, resulting in a decrease in effective stress. On the other hand, if the clay is relatively stiff, it will undergo minimal settlement, and the effective stress will remain almost the same.
Without further information about the settlement characteristics of the clay deposit, it is not possible to determine the exact value of effective stress after consolidation settlement is completed. Therefore, the answer cannot be determined based on the given information.
Thus, the value of effective stress after consolidation settlement is completed cannot be determined with the given information.

Effective stress immediately after fill = initial effective stress + increase in vertical stress
Effective stress immediately after fill = 200 kPa + 60 kPa = 260 kPa
Therefore, the value of effective stress immediately after the fill is placed is 260 kPa.
