带反弧角的直立堤平均越浪量计算方法比较

Comparison of calculating methods of mean wave overtopping on vertical breakwater with bullnose

反弧角对降低平均越浪量有良好效果,但不同的文献和规范给出的相关计算方法存在差异。根据国内外学者基于三维波浪模型的试验成果以及相关的规范、文献,并结合实际工程的物模试验,对带反弧角直立式堤平均越浪量的各种计算方法进行分析比较。结果表明,EurOtop法适用性广且结果贴近试验值,CEM法公式简单且结果保守,可为类似的港口工程提供参考。

Bullnose has a good effect on reducing overtopping,but there are differences in the calculation methods given by the documents and specifications.According to the experimental results of three-dimensional wave model by domestic and foreign scholars,the relevant codes and documents,combining with the physical model test of practical engineering,we analyze and compare various calculation methods of mean wave overtopping on vertical breakwater with bullnose.The results show that the EurOtop method has wide applicability and gives close results to the experimental values.The CEM formula is simple and has conservative results.It can provide references for the similar projects.
