中文摘要 | 本文應用Hsu等人(2003)所提出之EEMSE數值模式,探討波浪通過平面系列潛堤所產生的布拉格共振(Bragg resonace)效應,從數值計算結果分析系列潛堤共振效應和影響參數之關係,並據此選擇適當海域作為設計基地,進一步評估該工法之可行性。文中以新竹港南海域爲例,利用數值模式進行波場模擬,以遮蔽效益參數評估佈置系列潛堤後的消波效果。本文同時以該佈置方案爲例估算建構所需之材料成本,綜合歸納系列潛堤工法之優缺點,藉以說明其於海岸保護上之適用範圍。 |
英文摘要 | In this paper, the Bragg scattering for water waves propagating over a series of submerged breakwaters is investigated. Numerical schemes used in this study is based on the Evolution Equation of Mild-Slope Equation (EEMSE) developed by Hsu et al. (2003). Effective sheltering parameter is presented to assess the effect of wave reduction reflection for a series of submerged breakwaters. HsinChu Gangnan Coast using the numerical approach and the project cost an example of application is focused on estimate is also present for a series of submerged breakwaters. Finally, the advantages and disadvantages of using a series of submerged breakwaters are then compared. The results can help serve as an appropriate choice in favor of a series of submerged breakwaters for practical design. |
