Refer to the compression curve marked Soil 13 in Fig. 8.9a. Disregard the small unloading cycle in the middle of the curve. The initial void ratio for this soil is 1.17, and the pre-consolidation pressure is 290 kPa. The right-hand vertical boundary of this graph is at σ'vc = 2000 kPa.

Required:

(a) Determine the Cr and Cc for this soil based on the compression curve.

(b) If a layer of this soil 12 m thick is loaded from 50 to 800 kPa (two of the data points shown on the curve), what settlement will result, in m?
