| 摘 要： | 根据Gumbel分布和Clayton Copula函数构造出二维Gumbel Clayton Copula分布,根据渤海海域某观测站测得的1970—1993年年最大波高及风速,具体介绍该二维Gumbel模型在海洋工程设计中的使用方法。通过导管架平台基底剪力计算表明,使用该二维Gumbel模型所得的50a一遇剪力值降低了37%,对于边际油田,可以降低荷载设计标准,从而减少海洋工程的投资费用。

| Abstract: | This paper introduces bivariate Gumbel Clayton Copula distribution based on Clayton Copula function.This bivariate Gumbel Clayton Copula distribution is discussed according to a 24 a observed data.The data is measured by an oceanographic station in the Bohai area from 1970 to 1993,which contains annual extreme wave height and wind speed.Design parameters combinations are presented for the computation of the jacket platform base shear.The results reveal that the loads design criterion can be reasonably lower... |
