## Question:

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.
