为了研究作用于海上结构的主要极端作用,以短期测波资料为基础,将对海浪形成发展有重要影响的风速与波高、周期有机结合起来,推导出给定风速条件下的波高、周期联合概率分布模型,对波高、风速相关系数进行参数分析。将给定风速条件下N年最大波高作为滤过复合Poisson过程考虑,推导了其超值累积分布,进而反推台风时相应重现期下的年最大波高众值及相应特征周期,得出了基于台风环境的设计波浪要素。结果表明:推导模型从概率学角度建立了风、浪设计因素的对应关系,简化了传统设计参数的计算。
In order to study the main extreme role acting on the offshore structure, based on the short-term wave data, wind speed, wave height and period with important influence on sea wave formation and development are combined organically to deduce the wave height, periodic joint probability Distribution model, wave height, wind speed correlation coefficient parameter analysis. Considering the N-year maximum wave height under a given wind speed as the filtered composite Poisson process, the cumulative value distribution of the super-value is deduced, and then the annual maximum wave height value and corresponding eigenvalue under the corresponding recurrence time are derived. Design Wave Elements Based on Typhoon Environment. The results show that the derivation model establishes the correspondence between wind and wave design factors from the perspective of probability and simplifies the calculation of traditional design parameters.
