框架式消波堤消浪特性研究

Study on wave dissipation characteristics of frame breakwater

针对实际工程中应用的浮式消波结构,采用水槽物理模型试验的方法,对规则波作用下框架式消波堤的消浪效果进行研究,得出透射系数与浮堤相对宽度、管道排数以及管道公称外径的关系。结果表明,相对宽度是消波堤消浪性能最主要的影响因素,管道排数与管道公称外径也有明显影响,综合考虑用料等因素,建议选用模型3(6排、公称外径为40mm)的消波堤形式。

For the structures of floating breakwater which are used in practical engineering,we carry out the physical model experiments in the flume to study the dissipation effect of frame-type breakwater in the regular wave,and obtain the relationships between transmission coefficients and relative width of floating breakwaters,the number the row of pipelines and the nominal diameters of pipelines.The results show that the relative width is the main influencing factor for the wave dissipation performance of the breakwater.The rows number of pipelines and the nominal diameter of the pipelines also have significant impact on the wave dissipation.Considering the material and other factors,the model 3(6 rows,nominal diameter 40 mm)is recommended as the type of breakwater.
