THE IRREGULAR BREAKING WAVE FORCES ON VERTICAL WALL

A method for the calculation of total horizontal wave forces by irregular breaking waves on vertical wall was developed by authors, which was based on physical model test, dimensionless analysis and assessment of real construction. The methods for the determination of pressure distribution of horizontal forces on vertical wall as well as u-plift forces on the bottom of wall are also given. The comparison between calculated results by this method and samples of real construction are very well.

作用于直墙堤上不规则波破波波浪力的统计分布特性

根据不规则波破波波浪对直墙堤作用力的实验资料进行概率分析，本文指出概率分布可用威布尔分布表述，并提出了其形状参数ｍ与波浪要素和基床条件等参数的拟合关系，其尺度参数ａ可由ｍ值通过二者间的理论相关式求得，分析成果与实验结果符合良好。     

直墙波浪力计算中几个问题的探讨

由于近岸波浪动力受地形等主要因素的影响变化剧烈,尤其伴随着波浪破碎,增加了直墙上波浪力确定的困难。直墙上波浪力的确定在现阶段仍以物理模型试验为主。然而,不同的研究者所得的结果往往差异较大。文中通过物理模型试验,对直墙上波浪力计算中几个常见的问题进行了进一步的研究和探讨,提出同时刻压强沿水深的分布型式主要有局部冲击型、均匀分布型和过渡型三种。分析结果可为直墙波浪力更为准确的确定提供依据。     

Boussinesq方程的二阶椭圆余弦驻波解

等深浅水域中的流体运动可由Boussinesq方程描述.众所周知,该方程有行进波解(孤立波及椭圆余弦波).本文则以Boussinesq方程为控制方程,利用渐近匹配法对椭圆余弦波在直墙上反射进行研究,给出了反射过程中内、外场波形及速度变化的解析表达,从而得到了Boussinesq方程的二阶椭圆余弦驻波型的解析解,并讨论了这类驻波的若干性质.当波长无限增大时,所得解析解收敛于孤立波的情况.这些解析结果不仅有助于揭示岸坡对非线性浅水波影响的力学机理,在海岸防护和开发和岸壁附近结构物的设计条件等工程领域中也具有现实的指导意义.     

PROBABILITY DISTRIBUTION OF IN-LINE WAVE FORCES ON A PILE IN IRREGULAR WAVES

The probability distribution of in-line wave forces on a pile can bemathematically summed up to that of a theory and the assumption of wave period being constantare used and the above probability distribution is simplified to that of a single dimentsionfunction.The probability density functions of the peak values of total wave forces on a wholevertical pile in irregular waves are derived from that of wave height which is the Rayleighdistribution(deep water wave)or the Kerohovski distribution(shallow water waves)on the baseof the Morison Equation.The identification with experimental data shows that suchsimplification is successful.These distributions are compared with Weibull distribution andRayleigh distribution and the result shows that the shallow water distribution of wave forcesobtained here is the best one and can be used in practice.
