| Description | 本研究では，愛知県の巨大産業を支えるサプライチェーンを擁する地域のひとつである碧南市を対象として，南海トラフ巨大地震による地震動に対する堤体基礎の沈下量を数値解析によって評価した．この解析結果を津波氾濫解析に組み込むことで，堤体基礎の脆弱性が氾濫過程や浸水域に与える影響について検討を行った．堤体基礎の沈下や直立堤の崩壊を考慮することにより津波浸水域は大きく拡大することを定量的に示すことができた．このことは，沿岸構造物の耐震化の重要性を示していることはもちろんのこと，強震動による海岸・河岸構造物や堤体基礎部の脆弱性が津波ハザード評価に与える影響を無視できないことを示している．

| Description Alternative | In this study, the subsidence amount of a body structure caused by a strong motion at the Nankai Trough great earthquake was evaluated by GEOASIA numerical simulation. We investigated the influence on the tsunami inundation process and area incorporating the numerical results of the structural vulnerability appeared by the strong motion. The numerical results show that the tsunami inundation area was extended by subsidence of body structures and collapse of an upright dike. It proves the importance of not only earthquake resistance but also vulnerability evaluation of coastal and river-side structures due to a strong motion during the process of tsunami hazard evaluation.
