Question:

A consolidation test was performed on a specimen of inorganic clay 2.3 cm thick (doubly drained) and gave the following results: C rε = 0.043, C cε = 0.265, and σ'p = 75 kPa. The typical t100 in the recompression range was 8.4 min, and in the virgin compression range it was 32.5 min.
(a) If each increment is left on for 24 hours, determine the amount of secondary compression strain that will occur in both the recompression and the virgin compression ranges.
(b) One increment was left on at σ'v = 95 kPa for two weeks. What over-consolidation ratio resulted?
