摘　　要：文中通过改变格栅的宽度、浸深和格子的边长,构造出六种试验模型,通过物理试验,研究了这6种格栅模型的消波性能.在小型波浪水槽中,保持水深不变,进行不同周期和波陡的规则波系列试验,采用浪高仪测量波面抬高.消波性能主要由透射系数表达,计算了模型的透射系数,分析了宽度、浸深和格子边长等因素对透射系数的影响.结果表明:增加模型的宽度和浸深可以有效提升模型的消波性能.在三个格子边长中,两种较小的边长,消波性能接近,而最大的格子边长,消波性能变差.通过比较,推荐了消波性能最优的试验模型.By changing the width,immersion depth and side length of the grid,six experimental models were constructed.The wave attenuation performance of these six grid models was studied through physical experiments.In a small wave flume,regular wave series tests with different periods and steep waves were carried out while keeping the water depth constant,and the wave surface elevation was measured by wave height meter.The wave-absorbing performance was mainly expressed by transmission coefficient,and the transmission coefficient of the model was calculated,and the effects of width,immersion depth and lattice side length on the transmission coefficient were analyzed.The results show that increasing the width and immersion depth of the model can effectively improve the wave-absorbing performance of the model.Among the three grid side lengths,the two smaller side lengths have similar wave attenuation performance.However,the maximum grid side length makes the wave attenuation performance worse.By comparison,the experimental model with the best wave attenuation performance is recommended.
