中文摘要

本文主要是以有限差分法所建立的二維數值計算模式，來分析在造波板的運動下，潛堤、浮式防波堤與波浪間之互制(interaction)反應分析，其中考慮繫纜式浮體的三自由度藕合運動。模式中亦考慮完全非線性(fully nonlinear )效應的影響，最後據以進行完整的實例分析，以分析波浪與結構物間的互制關係。

英文摘要

A time-independent finite-difference numerical scheme is developed to study the dynamic response of a submerged and a floating breakwater under the wave loading of a fully numerical force. The coupled surge, heave and pitch motion of a floating breakwater and the wave-structure interaction are included in the model. The numerical results are validated uses several bench mark studies and results available elsemlse. The wave reducing effect of a submerged and a floating breakwaters were analysis and discusse.
