Abstract
The Hydroplane Tsunami Barrier is a kind of the movable breakwater. The main body is fixed to the pedestal by special rubber belts, and it rises by hydraulic force due to tsunami and storm surge. The effectiveness of this breakwater for tsunami countermeasures is indicated through experiments of response characteristics for hydraulic force, wave force acting on the main body and the damping effect for a wave height. This study aim to evaluate the performance of the Hydroplane Tsunami Barrier by using the full-scale model. As a result, it is revealed that the damping effect increases with the height of tsunami. Response characteristics evaluated by this study had good quantitative agreement with experiment results of 1/50 and 1/200 models.
