摘　　要：为了提高海堤设计中越浪量计算的精度,特别针对长周期不规则波的影响因素展开研究。运用FLUENT模型,对海堤越浪过程进行了准确模拟,并在不同波况下计算了海堤越浪量。通过对EurOtop(2018)越浪量计算公式的修正,大幅度提高了长周期波浪条件下越浪量计算的准确性。结果表明,波浪周期对海堤越浪量产生显著影响,尤其是在长周期不规则波的情况下,修正后的计算公式更为可靠。这一研究为海堤设计提供了更精确的越浪量计算方法,有助于提高海堤工程的安全性和可靠性。In order to enhance the precision of overtopping calculations in coastal embankment design,the influence factors of long-period iregular wave were studied especially.The FLUENT model was employed to accurately simulate the overtopping process along coastal embankments,and wave overtopping was calculated under various wave conditions.Through the refinement of the EurOtop(2018)overtopping calculation formula,the accuracy of overtopping calculation under long-period wave conditions has been significantly improved.The results demonstrate that wave period has a substantial impact on coastal embankment overtopping,particularly in the presence of long-period irregular waves.The modified calculation formula proves to be more reliable.This study provides a more precise method for calculating overtopping in coastal embankment design,contributing to increase safety and reliability in coastal engineering projects.
