Abstract

 Conventionally, for the estimation of a wave pressure to a structure by a tsunami, a method assuming hydrostatic pressure has been proposed. The method is adopted as a design guideline for the tsunami evacuation building. However, the method was targeted to the wall surface of a single structure. Verification under the condition that a plurality of structures are arranged is not sufficient. From this background, this study covers regularly arranged cylinder groups. The relationship between the installation interval of the cylinder, the generated wave pressure and the specific energy was studied by numerical calculation and model experiment. As a result, it was found that the wave pressure characteristics to the cylinder in the grid-arranged column group are strongly influenced by the lattice spacing.
