摘要
为提高透空式防波堤的消浪效果,提出了一种新型透空格栅板式防波堤结构。通过水槽试验,分析了该防波堤的消波性能,探讨了上下层平板相对间距以及格栅板间隙比等参数对防波堤透射系数和反射系数的影响。结果表明,该结构防波堤消波性能良好,且防波堤出水状态下的消浪效果要好于淹没状态;随着相对板间距的增大,防波堤透射系数变小;上下层各格栅板间隙比为0.1时,防波堤的消波效果最佳。
In order to improve the wave-dissipating performance, a new grille plate-type open breakwater is presented. Based on flume experiments, the wave-dissipating performance of this breakwater was analyzed, and the influence of parameters, including the relative spacing between the upper and lower plates and the gap ratio of the grille plate, on the transmission coefficient and reflection coefficient were investigated. The results show that the wave-dissipating performance of this breakwater is satisfying, and it is better when the breakwater is above the still water level than when the breakwater is submerged;the transmission coefficient of this breakwater decreases with the increase of relative plate spacing; and the breakwater performs best at a gap ratio of the top and bottom plates of 0. 1.
