柔性浮式防波堤消浪特性研究

针对圆柱形柔性浮式防波堤的消浪效果展开断面试验研究,分析其在规则波和不规则波作用下的消浪特性。通过大量水槽试验给出了圆柱形柔性浮式防波堤透射系数、反射系数、衰减系数与锚固方式、试验水深、相对宽度的变化关系。研究结果表明:该结构形式的浮式防波堤对短周期波浪消浪效果明显,而对长周期波浪消浪效果不佳;锚固方式和水深对消浪效果的影响较小;相对宽度是影响消浪效果的主要因素。研究成果可为由该结构连接成的"V"形浮式防波堤的锚固方式和摆放角度的设计提供参考。

Study on wave dissipation characteristics of flexible floating breakwater

The wave dissipation characteristics of a new type of breakwater with cylindrical flexible floating structure under regular and irregular wave were researched.Through the cross-section model tests in flume, the variation relation between the transmission coefficient, reflection coefficient, attenuation coefficient of the breakwater and the anchorage style, water depth and relative width of the structure wave were analyzed.The experiment results showed that this flexible floating breakwater has a favorable dissipation effect on short period wave, but less on long period wave;the relative width of the structure is the most important factor affecting the wave dissipation while the anchorage style and water depth have less effect on wave dissipation effect.The research results could provide references for the anchorage and placement angle design of the "V" shape floating breakwater linked by flexible structures.
