Outline of Final Research Achievements

Great earthquakes and floods caused by torrential rains, which have become increasingly severe in recent years, require the performance of river levees in Japan to allow deformation but not entire collapse. This so-called "robustness" in the framework of performance-based design, and is regarded as a principle performance requirement to ensure the safety of structures. In this study, we developed an analysis method that can predict the progressive deformation and collapse process (robustness) of river levees due to seismic motion, overflow and seepage flow. We also proposed a method to quantify the prediction accuracy of the proposed method through V&V (verification and validation). These results lead to the evaluation of the robustness of river embankments against floods and earthquakes.

Academic Significance and Societal Importance of the Research Achievements

現在まで,河川堤防を含む土構造物の変形を予測する種々の手法の開発が研究・開発されてきた.いずれも土の破壊までを予測することに主眼が置かれてきたが,破壊から破壊後の挙動までを追跡可能な手法には課題が残されていた.地震時や洪水時において,変形を許容しても完全な崩壊には至らない「粘り強さ(ロバスト性)」を評価するためには,破壊後の挙動の解析が重要であり,本研究ではこれを実現する手法を提案した.洪水・地震に対する河川堤防のロバスト性評価手法を構築することで,土構造物の性能設計法の確立という地盤工学における喫緊の分野課題の解決に寄与する成果を得た.
