Question
A 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)
