Outline of Final Research Achievements

In this study, the characteristics of tsunami loads acting on the multiple oil tanks have been investigated by using hydraulic experiments. The effects of tsunami incident angle β and the dimensionless adjacent oil tank spacing S/D on the tsunami pressures and loads were investigated. Furthermore, we have proposed the tsunami-resistant design of multiple oil tanks by setting the design tsunami loads as the multiplier of the single-tank case according to the position of oil tank.

Academic Significance and Societal Importance of the Research Achievements

本研究では、オイルタンク群に作用する津波波圧・波力の特性を把握し，複数棟オイルタンク配置の耐津波設計を提案した。研究成果により適切な設計基準に役立ちと考えられる。より安全で耐久性のあるオイルタンクの設計に寄与することが期待される。また，津波荷重の研究は津波リスク評価や防災計画の基礎となり，津波によるオイルタンク群の被害予測や適切な対策の策定に役立ちと考えられる。
