Abstract

 To investigate the geotechnical characteristics of embankment mounted with the dewatered clay lumps at seven years ago, the surface wave exploration, cone penetration tests and the consolidated constant pressure direct box shear tests on the block samples obtained from the embankment were performed.<br> As a result, the densities of embankment without a part of ground surface were kept the value at the construction. The rupture envelopes obtained from the direct box shear tests were located above the fail criterion of dewatered clay lumps at the design, it was therefore confirmed that the embankment at the present maintained its stability.
