摘要
以塘沽和龙口海洋观测站 2 0年极值增水值为样本 ,基于二维冈贝尔逻辑分布模式 ,探讨了不同海域风暴潮增水极值的联合分布规律。通过对二维分布的联合概率密度、条件概率密度和同现概率的计算 ,给出了相应的工程设计参数 ,供有关部门在防潮规划时参考。
By taking the annual maximum storm surges at Tanggu and Longkou Tidal Stations in 20 years as an example, this paper discusses the joint probability of extreme storm surges on the basis of the bi-variable Gumbel Logistic model. Corresponding engineering design parameters are given out by calculating the joint probability density function, conditional density function and probability function. Return period values of storm surges are proposed for reference in formulating storm-prevention program.
