直立式防波堤水平波浪力的概率分布

摘要

On the basis of physical model tests,studied is a probabilistic distribution of horizontal wave forces of irregular waves on vertical breakwaters.Through analysis,it is concluded that the horizontal wave force distribution is determined by the characteristics of wave forces. Impulse wave forces fit the double-parameter Weibull distribution,and impact forces deviate from the Weibull distribution.The calculation of the shape parameter and scale parameter shows that the two parameters are not fixed and that they are affected by sea state, breakwater geometry and water depth. According to the results,a formula is developed to determine the parameters.%试验研究表明，不规则波对直立式防波堤作用力的概率分布类型因波浪作用性质而变化，脉动力符合双参数的韦伯分布，冲击力偏离韦伯分布.经过统计分析，得出了每一种试验情况下韦伯分布的形状参数和比例参数，并研究了参数的变化规律，提出了直立式防波堤在不同波浪情况和水位条件下确定分布参数的方法.
