摘要
通过规则波作用下高桩梁板式透空防波堤断面波浪模型试验,重点研究影响防波堤透浪系数的主要因素(包括相对水深、相对透空率、入射波高和波周期等)及其规律,通过与现有防波堤透浪系数理论公式的对比找出误差原因。针对防波堤上部越浪的情况,考虑波浪超高和相对堤宽等因素的影响,修正防波堤透浪系数公式并进行验证。本研究成果可作为相关理论研究和工程实践的参考。
Trough the wave model test for the section of pile-stake permeable breakwater under the action of regular wave,the main factors such as the relative water depth,relative permeability rate,wave height and period affecting the wave transmission coefficient of the breakwater and the regulation are emphatically studied.Through the comparison with the existing breakwater transmission coefficient of theoretical formula,the reasons of difference are found.According the overtopping wave condition of breakwater and considering the affecting factors such as wave overheight and the relative width of breakwater,the formula will be revised and verified.The results can be taken as the reference for relative theoretical study and engineering practice.
