Description

The measure of floating objects is regarded as important to reduce the second damage caused by tsunami, but there is little knowledge about measures. In this research, the capture effect of containers is examined by hydraulic model experiments using the tsunami barrier. As a result, when pile pitch is smaller than the width of the container, the outflow rate depends on height of the pile and inundation. In addition, the outflow rate extremely tends to rise when the depth of the inundation more than a half of the height of the tsunami barrier. Thus, it is necessary to secure the height of pile of the degree to double of the inundation height in order to get a high capture effect.
