我国是世界上经常受风暴潮袭击的国家之一,因此,很需要计算每个测站《大增水值的重现期。首先,我们用耿贝尔方法,计算了资料序列长的17个站的最大增水值的重现期。在这些站计算的最大增水值的频率分布与由历史资料计算的重现期吻合得较好。其二,我们还用三种方法计算了海口站最大增水位的重现期并进行了计算结果的比较。最后,我们计算了湛江站的最高潮位的频率分布。其计算值与依据历史资料计算的重现期吻合得相当好。计算结果对做风暴潮预报、海岸工程设计和估计风暴潮造成的损失非常有用。
As one of the countries in the world that has been hit by the storm surge frequently, it is very important to calculate the "return period of major water recharge values at each station. First, we calculate the reappearance period of the maximum water recharge value of 17 stations with long data series by using the method of Gumbel. The frequency distribution of the maximum water-recharge value calculated at these stations agrees well with the re-calculation calculated from historical data. Second, we also calculated the return period of the maximum water level increase in Haikou Station by three methods and compared the calculated results. Finally, we calculate the frequency distribution of the highest tide level at Zhanjiang Station. The calculated values are in good agreement with those calculated based on historical data. The results are useful for storm surge forecasting, coastal engineering design and estimating the damage caused by storm surges.
