抄録

The tsunami generated by the 2011 off the Pacific Coast of Tohoku earthquake caused massive damage to coastal dikes. In order to protect human lives and properties from tsunami, the tenacity of coastal dikes should be improved to secure sufficient time for evacuating residence. In this study, clay or lean cement mixed soil are used for embankment materials. The embankment materials of coastal dikes that can enhance its tenacity are investigated by means of both laboratory experiments and numerical simulations. It was cleared quantitatively from laboratory experiments that tenacity of coastal dikes was improved by using clay or cement mixed sand for embankment materials. In addition, the results from numerical simulations show that the coupled fluid-sediment interaction model considering clay cohesion has possibilities of evaluating the tenacity of coastal dikes composed of clay mixed sand.
