浮式防波堤設置在開闊海域，以作消減波浪之用，其材質以能抗浪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，使用抗浪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56%。
用廢輪胎浮式防波堤於流速較低及波高較大時之模擬海況下具最佳之消波能力，例如於流速(V)＝5cm/sec及波高(H)＝15cm、攻角90°模擬海況下，消波率為73.2%，可見其消波之效能極佳。於高流速及大波高之模擬海況下，消波率則相對較差，例如攻角90°、流速(V)25cm/sec、波高(H)5cm情況下消波率最差(37%)，餘皆在50%左右。

The floating breakwater was installed in the open sea area for reduceing the attack by the wave, so the material of the floating breakwater has to resist the attack of the wave and erosion. The waste tire had been to design in the study.
The floating waste tire breakwater was set up in the water tank for experiment. The results indicated that It has been improved the stable mooring rope system reducing 56% instantaneous tension of the floating breakwater under the interaction.
The maximum wave eliminate rate occurred when the flow velocity was low and wave height was high. For instance, if flow velocity(V) is 5cm/sec ,wave height(H)is 15cm and the attack anger is 90° , the wave eliminate rate is 73.2%.
The floating breakwater con’t perform so well when the flow velocity (V) and wave height (H) are high. For instance, if V is 25cm/sec ,H is 5cm, and the attack anger is 90°,the wave eliminate rate is only 37%, The wave eliminate rate will be around 50% under other conditions.
