| 中文摘要 | 浮式防波堤設置在開闊海域,以作消減波浪之用,其材質以能抵抗波浪及海流之侵襲且耐侵蝕者為佳,本研究以廢輪胎為研究標的。廢輪胎浮式防波堤於水槽實驗中,得知在海流及波浪之交互作用下,使用穩定式繫留系統可將浮式防波堤於波流互動下之瞬間張力減小至57%。用廢輪胎浮式防波堤於模擬海況流速較低及波高較大時,具最佳之消波能力,例如於流速(V)=5 cm/sec、人造波高(H)=15 cm之模擬海況下,穩定式繫留索之瞬間張力僅達傳統繫留索之57%。而穩定式繫留索之廢輪胎浮式防波堤波浪透過率(0.27)則為使用傳統繫留索波浪透過率(0.24)之112%,波浪透過率越小其消波能力越佳,基於消波率與安全性之考量,本研究可提供業者參考與選擇。 |
| 英文摘要 | Floating Breakwater set up at open sea area that was to reduce the wave energy. The material of the Floating Breakwater can resistance the attacks from wave and current, and endure erosion. This research used scrap tires as research material. In this study, the wave-attenuation coefficients of Floating Tire Breakwater (F T B) with two types mooring system were determined based on the results of laboratory experiments. The results showed that the FTB was able to reduce the wave action effectively. The stable mooring rope was able to reduce the instantaneous tension of the FTB significantly. The best wave transmitted coefficient (Kt) could obtained under the larger wave height (H) and low flow speed (V). In the case of V = 5 cm/sec and H = 15 cm, the wave transmitted coefficient (Kt) of the stable mooring rope (0.27) was raise to 112% compared with traditional mooring rope (0.24), but the instantaneous tension of stable mooring rope was reduce to 57% of the traditional mooring rope did. In this study, the efficiency and safety of Floating Tire Breakwater was considered, this research can provide the useful references for further development of Floating Breakwater design. |
