The ultimate consolidation of a 13-ft thick single-drained clay layer (cv = 0.1 ft2/day) was calculated to be 0.813 feet.

a. What is the average degree of consolidation for the clay layer when the settlement is 2 inches?

b. If the average value for cv for the pressure range is 0.003 cm2/second how long will it take for 50% settlement to occur? (be careful on the units)

c. If the 17 ft clay layer is drained on one side, how long will it take for 50 percent consolidation to occur?

A 10-ft-thick silty clay layer is subjected to a load that results in total primary consolidation settlement of 0.85 inches. The clay is sandwiched between two sand layers and has an initial void ratio of 0.76, a coefficient of compression of 0.45, a coefficient of recompression of 0.07 and a coefficient of consolidation of 0.034 in2 /year. Calculate the settlement at the end of 2 years and determine the time in days for 0.60 inches of settlement.

Consider a clay layer that is 1 m thick. The clay has a compression index of 0.35, a swell index of 0.07, a permeability of 4 x 10-7 cm/sec, a preconsolidation pressure of 172 kPa and a coefficient of consolidation of 2.7 x 10-4 cm2/min. The initial effective stress at the midpoint of the layer is 140 kPa, and the soil has a void ratio of 1.01. The stress is increased to 200 kPa. The soil is drained above and...
