| 摘 要： | 为了研究波浪非线性对爬高的影响，解决防波堤等工程设计的实际问题，通过对数学模型试验、物理模型试验、规范公式得到的防波堤波浪爬高对比分析，分析了非线性主要影响参数厄塞尔数、相对水深和波陡对波浪爬高的影响规律，指出规范公式计算时存在的缺陷，并对其计算公式、适用范围进行修正、拟合，得到了强非线性规则波浪爬高的计算方法，可适用于斜坡堤断面的波浪爬高计算，与物理模型试验和数学模型试验结果对比表明，新的波浪爬高计算公式具有较好的计算精度，研究结果可为防波堤等实际工程设计提供重要参考。

| Abstract: | In order to study the influence of wave nonlinearity on wave run-up and solve the practical problems of breakwater design, through the comparative analysis of mathematical model test, physical model test and wave run-up of breakwater with standard formula, the influence law of main nonlinear influencing parameters, such as Ur, relative water depth and wave steepness, on wave run-up is analyzed, and the defects in calculation of standard formula are pointed out. The calculation method of strong nonlinear regular wave run-up is obtained by modifying and fitting its calculation formula and applicable scope. It can be applied to the calculation of wave run-up of sloping breakwater section. Compared with the results of physical model test and mathematical model test, the new formula has good calculation accuracy, and the research results can provide important reference for the design of breakwater and other practical projects. |
