摘　　要：通过斜坡式防波堤物理模型试验,研究堤后次生波波浪透射系数的变化规律,建立了堤顶相对出水高度H_(c)/H_(s)和相对堤顶宽度B/H_(s)与波高透射系数的关系并拟合非线性回归公式。同时采用本文拟合公式和经验公式对不同工况下的堤后次生波波高进行计算,并与试验结果对比。结果表明,本文拟合公式与试验结果最为吻合,具有良好的适用性,然后分析了其他经验公式计算结果的差异性。该成果可为工程实际以及由斜坡式防波堤堤顶允许越浪生成的堤后次生波计算提供参考依据。After studying the variation law of the secondary wave transmission coefficient behind the breakwater by the physical model test of the sloping breakwater,this study establishes the relationships of the relative outlet height H_(c)/H_(s)and the relative levee top width B/H_(s)with the wave height transmission coefficient,and fit the nonlinear regression formula.At the same time,the fitting formula in this paper and the empirical formula are applied to calculate the height of the secondary wave behind the breakwater under different working conditions,and the results are compared with the test results.The results show that the proposed fitting formula is the most consistent with the experimental results and has good applicability.Then,the differences in the calculation results of other empirical formulas are analyzed.The results can provide a reference for engineering practice and the calculation of the post-dike secondary wave generated by the allowable surge at the top of the sloping breakwater.
