normally consolidated clay in the field has the following properties: Compression index = 0.26 Initial void ratio (eo) = 0.85 Effective stress at the middle of the clay layer = 136 kPa Average increase in vertical pressure (AP) = 45 kPa Secondary compression index (Ca) = 0.02 Thickness of the clay layer = 3.10 m a. Solve for the expected settlement due to primary consolidation (0.054m) b. Solve for the secondary consolidation settlement after 6 years assuming that the primary consolidation settlement is completed after 2 years. (0.054m) c. What is the total consolidation settlement of the clay layer after 6 years? (0.108m)
