Soil Mechanics Mini-assignment

Evaluation of Consolidation Parameters and

Calculation of Soil Settlements

Your Tasks for Part A

Using the data/measurements provided, evaluate the values of the compression index Cc, the swelling index Cs, the coefficient of consolidation cv of the undisturbed clay sample A.

Your Tasks for Part B

(a) By treating the clay as one single layer, calculate the settlement of the

warehouse due to the primary consolidation of the normally consolidated clay

layer. Assume the sand layers above and below the clay layer do not undergo

any compression.

(b) What is the expected settlement of the warehouse after two years, that is, at

time t = 2 years?

(c) How long does it take for the settlement of the warehouse to reach 90% of

the primary consolidation settlement calculated in part B(a)?
