摘要
针对一种新型的浮式梳式防波堤的消浪性能进行模型试验研究,试验模型采用固定结构形式,分析相对宽度、相对波高、水流速度和不规则波等因素对透射系数、反射系数和耗散系数的影响.研究结果表明:浮式梳式防波堤的消浪性能较为稳定,在波长较大的情况下,该型防波堤的消浪性能优于相同尺寸的方箱式防波堤;当相对宽度为0.20～0.27时,透射系数能达到最小值;在波与流共同作用下,同向水流会削弱波浪的消浪性能;在相同波浪参数下,不规则波的透射系数要略高于规则波的透射系数.
Abstract
Aiming at the wave dissipation performance of a novel floating comb-type breakwater fixed in the flume based on model tests.The effects of relative width,relative wave height,current velocity,and irregular waves on the transmission coefficient,reflection coefficient,and dissipation coefficient are investigated.The findings indicate that the floating comb-type breakwater exhibits consistent wave dissipation performance,as evidenced by a lower wave transmission coefficient compared to a similarly sized rectangular floating breakwater for long period waves.Furthermore,the relative width range of 0.20～0.27 yields the minimum transmission coefficient.The superimposition of bidirectional currents diminishes the performance of wave dissipation.When comparing irregular waves to regular waves with identical parameters,the transmission coefficient for irregular waves is marginally higher than that of regular.
