Abstract:
沿岸地區常設置各式海岸工程構造物，如防波堤與海堤，以反射或消散波能，從而保護海岸線並維繫地方經濟活動。掌握波浪與結構物之間的互動機制，對諸多工程應用至關重要，尤以處理極長週期波相關議題時更顯關鍵。 本次演講將綜述我們在「波浪—結構物互動」方面的研究，重點聚焦孤立波與海岸結構物互動的實驗觀測與數值模擬。大尺度實驗揭示孤立波於緩坡上的運動學特徵；小尺度試驗則探討其與海堤及薄障壁互動時的動力學響應。此外，並將從模型適用性的角度說明數值模擬方法。最後，將簡要介紹目前進行中的研究主題。
Coastal regions commonly employ engineering structures—such as breakwaters and seawalls—to reflect or dissipate wave energy, thereby protecting shorelines and supporting local economies. Understanding wave–structure interactions is crucial for many engineering applications, particularly those involving long-period waves. This talk surveys our work on wave–structure interactions, emphasizing experimental observations and numerical modeling of solitary-wave dynamics. Large-scale experiments characterize the kinematics of solitary waves propagating over gently sloping beaches, while small-scale tests probe the dynamic responses during interactions with seawalls and thin barriers. We also discuss numerical simulations with an emphasis on model applicability. Finally, we briefly introduce several ongoing lines of research.
