• 中文摘要： 本文探討多數二維無限長結構物與斜向線性規則入射波之交互作用。利用邊界阻尼與有限元素法來解析波浪繞射、漫射問題。文中計算(1)雙銅體型，二互不連接結構物之交互作用；(2)浮動式結構物與一滲透性直立式碼頭之交互作用；(3)繫泊與結構物間互制力之影響。本文之有限元素解亦與已知之多數奇異解、邊界元素解等互相比較，以證實其準確性
• 英文摘要： The hydrodynamic interaction phenomena arising from multiple two-dimensional horizontal cylin-ders interacting with obliquely incident linear monochromatic waves are treated. A finite element method(FEM) incorporating radiation boundary dampers is employed to solve the corresponding diffraction andradiation boundary value problems. Numerical results of a rigidly connected catamaran and two freelyfloating cylinders are compared with those obtained by the method of multipoles. Numerical predictionof interaction effects between a floating structure and a vertical wall are given and compared with thoseobtained by the boundary element method; permeability of wall is also included in this study. The effectsof moorings and inter-structural constraints on the structural response are also calculated.
