| 摘 要： | 针对工程中应用较广的透水抛石堤结构,通过一系列断面模型试验方法,研究了抛石堤块体尺寸D与静水面堤宽Bswl之比与无因次波陡H/(gT～2)之间的关系。在前人研究成果基础上提出了改进的透浪系数计算公式。试验及分析结果表明,该公式能较好地计算规则波作用下抛石堤堤后透浪系数,可为相关工程设计提供参考。

| Abstract: | For the structures of permeable breakwater which are widely used in practical engineering,the relationship between the ratio of block diameter of core material to the equivalent width of dike D/Bswl and the dimensionless wave steepness H/(gT2) is analyzed through a series of sectional model tests.We propose improved empirical formulas of the transmission coefficient of permeable breakwater based on previous researches.The results and analysis show that the formula can be used to calculate the transmission coefficient of the permeable breakwater under regular waves ,and can be used for future reference in relevant engineering design. |
