Abstract
The 2011 off the pacific coast of Tohoku earthquake (Mw=9.0) caused great damage to geotechnical structures in the vicinity of the eastern coasts. In contrast, many of reinforced soil walls constructed along the coast were less damaged by the tsunami. In this study, assuming that tsunami overflow force does not have effect on reinforced soil wall, we conducted a model flume test to evaluate the behavior of a reinforced soil wall under strong water flow and water pressure induced by tsunami. It was found that the reinforced soil wall does not have large deformation unless there are some opening in the front panels and the flow out of backfill soils. Furthermore, we present the consideration of seismic evaluation of reinforced soil wall based on the result of experiments.
