A great amount of investigations were made at home and abroad for the wave overtopping of coastal engineering and several methods for calculating mean wave overtopping were proposed. Because affecting factors considered are different ,the results are quite different too. By now, in the design of most China coastal engineering such as seawall and revetment, ‘allowing wave overtopping’is used as the control condition to initially determine seawall top elevation,then the physical model test is applied to verify it. Based on the 3-D wave model test and synthesizing main researching deliverables for the mean wave overtopping on the slopping seawall ,the various methods are analyzed and compared each other,the suitable method is proposed for different situations, which will provides the reference for the similar project.%针对海岸工程中的越浪量问题,国、内外学者进行过大量研究,提出了多种计算平均越浪量的方法,但由于考虑的影响因素不同,计算结果常有较大差异.目前,在我国的海堤、护岸等海岸工程设计中,多按"允许越浪量"为控制条件初步确定堤顶高程,再由物理模型试验加以验证.本研究基于三维波浪模型试验,综合针对斜坡堤上平均越浪量的主要研究成果,对各种计算方法进行分析比较,并针对不同情况提出适用计算方法的建议,供工程设计参考.
