防波堤越浪量计算方法的试验验证与分析

Experimental verification and analysis of calculation methods for wave overtopping of breakwater

依托防波堤断面波浪物理模型试验项目,测定不规则波作用下3个防波堤(优化)断面和极端高水位、设计高水位下的堤顶越浪量。引用EurOtop2018、Gallach-Sanchez、水文规范公式和XGB-Overtopping神经网络工具计算6个工况下的越浪量计算值。通过试验测定值的验证,分析各计算方法在该项目涉及条件下的越浪量计算水平。结果表明,EurOtop2018和Gallach-Sanchez公式在我国斜坡式防波堤设计中仍具有一定的参考价值。

Based on the wave physical model test project of breakwater section,the wave overtopping of three breakwater(optimized)sections and two water levels of extremely high and designed high water level under the action of irregular waves were measured.EurOtop2018,Gallach-Sanchez,hydrological standard formula and XGB-Overtopping neural network tool were used to calculate the value of wave overtopping under six working conditions.Through the verification of the measured values of the test,the calculation level of overtopping of each calculation method under the conditions of the project was analyzed.The results show that EurOtop2018 and Gallach-Sanchez formulas still have a certain reference value in the design of sloping breakwaters in China.
