摘　　要：越浪对港内建筑物、船只和人员的安全构成威胁,也是导致海堤破坏的重要原因之一。因此,对越浪量的研究十分必要。基于某斜坡式防波堤的物理模型试验,得出相应的试验越浪量。同时针对堤前水位等影响因素,选取国内外经典的防波堤经验公式,结合试验数据对各公式进行误差分析。结果显示:根据室内模型试验的限制范围,陈国平公式误差较小;VAN DER MEER的平均值方法计算结果整体上偏低于试验值;OWEN公式受波浪周期的影响较大,当波浪周期较大时,计算误差较大。The amount of wave overtopping was studied by conducting physical experiments on a sloping breakwater,and the corresponding test wave overtopping was obtained.The classic wave overtopping empirical formulas from domestic and international sources were selected based on influencing factors such as the water level in front of the embankment.An error analysis was carried out for each formula in combination with the test data.It was found that within the limitation range of the indoor model test,Chen Guoping′s formula had a small error.The calculation results of Van der Meer's average method were generally lower than the experimental values.Owen′s formula was found to be greatly affected by the wave period,with significant calculation errors occurring when the wave period was large.
