摘　　要：针对沿岸海洋工程重现期风暴潮计算,提出一种计算方案,利用风暴潮数值模式计算出工程点每年最大的风暴潮序列,然后利用该序列进行统计分析。通过对广东阳江市沙环案例计算分析,结果表明:该方法与传统方法相比,精度相当,但是对于无长时间序列验潮资料的工程点,特别对于附近也无长时间序列验潮资料的工程点,其重现期风暴潮的计算方法,具有很大优势,计算结果具有很好的参考价值。For the return period of storm surge of coastal engineering, in this paper, a new method is proposed. First, the maximum storm surge of each year on engineering spot is calculated by using the storm surge numerical model, and the return period of storm surge on engineering spot is computed easily. We have studied the case of Shahuan of Yangjiang in Guangdong Province. The result shows that the precision of new method is equivalent to that of usual method. Therefore, it is very useful to calculate return period of storm surge at those engineering spot without many tidal data, also no many tidal data near engineering spot by using the new method.
