| 摘 要： | 对外海轻型码头结构的波浪荷载和海流荷载进行了统计分析。给出一个波浪周期内,波浪荷载的均值系数和变异系数随相位角的变化,进而得出50年设计基准期内波浪荷载的均值系数和变异系数。使用Monte-Carlo方法研究了波浪荷载的概率分布类型。利用海洋平台已有的研究成果,给出了50年设计基准期内海流荷载的均值系数和变异系数。结果表明:对于外海轻型码头结构,可认为波浪荷载和海流荷载均服从极值I型分布;50年基准期波浪荷载的均值系数为1.166,变异系数为0.263,海流荷载的均值系数为1.269,变异系数为0.142。

| Abstract: | A statistical analysis is conducted on the wave load and ocean current load for open sea small wharf,which concludes that the coefficient of mean value and coefficient of variability for wave load changes with phase angle within a wave period,and thus obtaining the coefficient of mean value and coefficient of variability for wave load in the reference period for 50 years design.The Monte-Carlo methods are used in study of probability distribution pattern of wave load,and the existing research achievements o... |
