Abstract

In the Great East Japan Earthquake that occurred in March 2011, the tsunami caused secondary damage such as oil spills and tsunami fires caused by the sliding and drifting of oil tanks installed in coastal areas. It is expected that the Nankai Trough earthquake and the tsunami caused by it will occur in the future, and such a disaster is one of the concerns even in Osaka Bay, which has many petrochemical complexes and oil tanks in the coastal area. Is. Therefore, it is considered effective to evaluate whether oil tanks, etc. slide or drift when a tsunami strikes, and whether or not oil spills occur due to this. In this paper, the tsunami fluid force exerted on structures such as oil tanks when a tsunami strikes is evaluated from an experimental and numerical standpoint. The safety standards of the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications and the tank model or tank numerical model drift (slide) due to the tsunami flow. ) We decided to investigate based on criteria such as whether or not to do so.

2011 年3 月に発生した東日本大震災では，津波により沿岸域に設置された石油タンク等が滑動・漂流することにより油流出や津波火災が発生する二次被害が発生した．今後，南海トラフ地震とこれに起因する津波が発生することが予想されており，沿岸域に多くの石油化学コンビナートや石油タンク等類を有する大阪湾でも，このような災害は懸案事項の一つである．したがって，津波来襲時に石油タンク等が滑動・漂流するのか，これにより油流出が発生するか否かを評価しておくことは有効であると考えられる．本稿では，津波来襲時に石油タンク等の構造物に及ぼす津波流体力を実験的・数値的立場から評価するが，総務省消防庁の安全基準とタンク模型あるいはタンク数値モデルが津波流れによって漂流（滑動）するか否か等の基準で調査することとした．
