When a saturated clay is sampled in an undisturbed manner from a bore hole, the sample extends vertically and shrinks horizontally under undrained conditions due to stress release. The conventional consolidation test specimen is trimmed from the expanded sample so that its diameter is equal to the inner diameter of the consolidation test ring, and this test procedure does not reproduce the actual consolidation behavior. The measurement of sample extension was conducted by means of overcoring method showed that the extension strains were 1 to 2%. To simulate the in-situ consolidation behavior, we proposed the consolidation test method that uses a specimen with a slightly smaller diameter than the inside diameter of consolidometer so that the specimen expands laterally to the inside of the ring.
