摘　　要：通过物理模型试验,研究不规则波作用下海堤越浪量,结果表明越浪量与爬高的影响因素基本相同,随各主要因素的变化规律也十分相似,采用波浪爬高和堤顶超高2个主要因子可较好反映越浪量的变化规律。提出了不规则波越浪量的计算公式,并根据越浪量对堤后不同防护情况下的冲刷破坏情况,提出了允许越浪量标准,为工程设计提供参考。Based on the physical model test,we carried out a research on the wave overtopping of sea wall with the irregular wave.The results show that the influence of the wave overtopping is basically the same to the wave run-up and so does the change rule.The wave run-up and the levee free-board can reflect the wave overtopping changes preferably.A new calculation formula on the irregular wave overtopping is set out and the acceptable wave overtopping under different protective conditions is given,which may serve as a reference for the engineering design.
