Figure shows the 1-D compression curve for a clay.

(a) Using log interpolation between 100 and 1000, determine the σ’u value at a vertical strain, eu = 20%.

(b) If the initial void ratio, eo = 0.846, determine Cr and Cc for this soil. For Cc, use the portion of the curve between σ’u = 200 and 800 kPa.

---

(c) If the original clay layer thickness is 9.5 m, determine the settlement that occurs in the layer when it is loaded from 70 to 200 kPa. (Note: You don’t need the results from part (b) to do this.)
