中文摘要 | 本文以港池振盪問題之數值模擬計算為主題作論述,文章的內容包括緒論、等水深邊界元素法數值模式、任意水深有限元素法數值模式、實際港池模擬計算案例、以及對於本文主題之結論。於緒論中言明港池振盪計算之主要目的,並藉由文獻回顧說明港池振盪計算在概念上及方法上的發展。等水深模式可說是港池振盪數值計算之基礎,本文以邊界元素法為軸心說明數值模式之架構。而任意水深港池振盪數值模式則是在數值計算上選擇有限元素法作說明。在實際港池模擬計算方面本文以花蓮港作案例,說明模式於實際應用上應有之考慮及作法。由本文計算結果顯示,配合模式理論架構以及考慮港池開口前方海域地形變化,將更能表現實際港池振盪之物理現象。 |
英文摘要 | The subject of this paper is on numerical simulation of harbor resonance. The contents include introduction, boundary element modeling of constant depth, finite element modeling of arbitrary depth, numerical calculation of Hwa-Lien harbor, and finally the conclusion. In introduction, the purpose of simulation of harbor resonance is stated, and development and conceptual evolution on numerical modeling are reviewed. In numerical modeling a boundary element method is introduced for constant depth problem, which is fundamental, whereas a finite element method is stated for arbitrary depth problem. In numerical calculation, Hwa-Lien harbor is used as an example to demonstrate what should be the consideration and corresponding solution in practical application of numerical model. The present computational results indicate that the numerical model can simulate better the physical phenomena of harbor resonance, by following theoretical structure of the numerical model and considering coastal bathymetry in front of the harbor opening. |
