The hydraulic consolidation test is used to determine thc consolidation properties of very soft clays under a low stress level. This test method consists of measurements of seepage flow velocity, distributions of pore water pressure and water content along the specimen depth, and the height of the specimen consolidated from the slurry clay under the seepage force and selfweight of the specimen. However, in this test method, the upper part of the specimen tends to separate from the inner surface of specimen cylinder during consolidation, resulted in a frustum shape with a concave surface at the top; the outer part of the specimen unable to maintain the one-dimensional consolidation state. Thus the measurements are made in the central area where the pervious bottom base is separated from the surrounding area by a circular insulation wall. The tentative test manual was already proposed, however, further amendments of the test method are presented together with some test data.
