| 摘 要： | 基于大型水槽试验结果，分析了不同海堤相对出水高度的波浪溢流量特征并进行分类；依据此分类方式，使用韦伯分布对大型水槽试验测得的波浪溢流量进行拟合，研究单个波浪溢流引起越堤流量的分布和瞬时越堤流量的分布，提出了新的经验公式。结果表明，新的经验公式与现有的方法相比提高了对波浪溢流过程中单个波浪溢流引起越堤流量和瞬时越堤流量分布的估算精度。

| Abstract: | Based on the results of full-scale flume tests, characteristics of combined wave and surge overtopping at relative freeboard were analyzed and classified. According to this classification, discharges of combined wave and surge overtopping measured from the full-scale flume test was fitted with the Weibull distribution, and distributions of individual overtopping volumes and instantaneous overtopping discharge were studied respectively. New empirical equations have been proposed to estimation the distribution of individual overtopping volumes and instantaneous overtopping discharge, which improved the estimation accuracy of them compared with the existing methods. |
