• 中文摘要： 本文提供在有限水深中突出柱狀形結構物了波浪繞射之邊界有限元素解法，文中利用一次與二次邊界有限元素求解數值結果，比較本文之結果與理論解，積分式數值解，相當吻合。利用邊界有限元素法，繞射波力之計算與一般積分式數值法所耗運算時間相當，但波壓之分佈計算則以本方法較為準確。
• 英文摘要： A numerical calculation procedure is presented for computing the wave diffraction by surface-piercingstructure in an ocean of finite depth by the Boundary Finite Element Method (BFEM). Both linear andquadratic boundary finite elements have been investigated. Comparisons between the present results withresults available from analytical and integral equation methods are good. The effort required for diffractionforce calculation is similar to the usual integral equation discretization procedure, however, the evaluationof pressure distribution is more accurately predicted when a smaller number of boundary finite elementsis used.
