国内外斜坡式防波堤越浪量计算方法比较

国内外斜坡式防波堤越浪量计算方法不同,选择合适的计算方法来准确计算与评估斜坡式防波堤越浪量非常必要。依托某海外集装箱码头扩建项目防波堤工程,详细介绍了国内外常用的防波堤越浪量计算方法,并结合2D防波堤越浪量物理模型试验,就各个计算方法计算值与试验结果进行了比较分析。结果显示:欧标中EurOtop (2016)在计算斜坡堤越浪量时具有更好的适应性,平均值方法较试验值偏小、设计评估方法较试验值偏大;而美国CEM方法和日本OCDI方法与试验结果相差较大。研究结果可为斜坡式防波堤设计与施工期安全评估提供参考。

Comparison of calculation methods for overtopping of armored rubble slopes at home and abroad

There are different methods for calculating the overtopping of armored rubble slopes at home and abroad.It is necessary to select an appropriate method to accurately calculate and evaluate the overtopping of sloping breakwaters.Relying on the breakwater project of an overseas container terminal expansion project,the calculation methods of overtopping of armored rubble slope commonly used at home and abroad are introduced in detail.Combined with the physical model test of 2D overtopping,the calculation values of each calculation method and the test results are compared and analyzed.The results show that EurOtop(2016)in the European Standard has better adaptability in calculating the overtopping of armored rubble slope,the average method is smaller than the test value,and the design evaluation method is larger than the test value;while the CEM method in the United States and OCDI method in Japan are quite different from the test results.The research results can provide references for the design and construction safety assessment of sloping breakwaters.
