中文摘要 | 本研究利用方向頻譜探論離岸堤周圍波場的特性。首先在水槽裡進行僅有一個單一的離岸堤的試驗。利用堤前的方向頻譜在方向域裡分離向堤和離堤波能量;並藉著比對堤前和堤後波場能量而得到堤體距離和波浪方向性的關係式。接續再以八斗子漁港離岸堤模型試驗結果驗證此兩關係式應用的可行性。不論從趨勢或是相對誤差的結果來看,以回歸式所推估的結果與實測值皆比極為相符。 |
英文摘要 | Using the concept of directional wave fields, the characteristics of the wave field around a detached breakwater were studied. At first, qualitative experiments were carried out for the case where a breakwater is the sole factor affecting the wave field. With the aids of these estimated directional spectra, outgoing and incoming wave energies in front of the detached breakwater were then separated in the spatial domain. Relationships between the wave energies, the distances of the measuring stations to the breakwater, and the directionality of the wave field were obtained. These results were then applied for the experiments where the fishing harbour Ba-Do-Zhi (BDZ) was used as model. Comparisons of results predicted by the empirical relations and those from the measurements are favorable. It is therefore proposed that the relationships presented here in this paper can be used for engineering purposes. |
