Abstract

 Authors carried out hydraulic experiments to clarify the dependency of passage rate, blocked rate and residual rate of tsunami floating bodies to or on a bridge deck upon tsunami peak velocity and tsunami averaged velocity, and inundation front height and rear height of a bridge deck. The share of passage rate of tsunami floating bodies with impact to a bridge deck and without impact of a bridge deck when tsunami peak velocity increases was clarified and in contrast physical mechanism on blocked rate of tsunami floating bodies to a bridge deck was discussed. In addition, residual rate of tsunami floating bodies on a bridge deck was found to become about 10% - 20% which is dominant of relatively small-sized tsunami floating bodies when tsunami peak velocity becomes high.
