| Outline of Final Research Achievements |
During the 2011 off the Pacific coast of Tohoku earthquake, coast and river levees caught the influence of external force by tsunami as well as earthquake. However there were few studies on seepage and overtopping performance of damaged levees after earthquake against tsunami and rainfall. In this study, we investigated seepage performance of deformed levees after shaking and evaluated durability of deformed levee under plural external forces such as earthquake and tsunami using centrifugal model tests and numerical simulations. We examined the effects of some experimental parameters such as input motions and water rising velocity on the seepage performance. The centrifugal model tests showed that seismic deformation changed the seepage performance of levees, and progressive failure during seepage might occur at the downstream side of levee slope. The numerical simulations showed that factors except for configuration change might affect the seepage performance of deformed levee.
