Abstract
River dykes and road embankments are frequently damaged during earthquakes. The liquefaction of foundation, the behavior of which is not yet well realized, is considered to be the main cause of the damage. Based on the results of past studies, the foundation of an embankment was divided into three zones to examine the failure modes. One-dimensional on-line earthquake tests, which were conducted by a combination of element tests and computer earthquake response analyses, were performed for such zones of actual river dykes damaged during earthquake. The cumulative horizontal displacement values obtained by the tests were compared with the measured embankment-crest settlement data, which showed that the liquefaction sliding failure under the toe of slope of such an embankment is found to be the most detrimental of all failure modes.
