For the consolidation test data given in Problem 11.11,
a. Determine the coefficient of volume compressibility for the pressure range stated.
b. If cv = 7 x 103 cm2/sec, determine k in cm/sec corresponding to the average void ratio within the pressure range.
In problem 11.11
Undisturbed clay has a preconsolidation pressure of 100 kN / m2. A laboratory consolidation tests yield the following data:
e σ' (kN/m2)
0.92.................150
0.77.................300
Determine the void ratio that corresponds to a pressure of 450 kN / m2.
