摘要
采用理论分析的方法研究了斜向规则波与无限多带横隔板的双层全开孔沉箱相互作用。依照结构的几何形状,整个流域被分成无限多个子域,在每个子域内应用特征展开法对速度势进行展开。对于沉箱内的波浪运动状态,引入相位差的概念,同时,在构造反射波模型时,考虑了结构物的几何形状影响。最后采用了不同的方法对该结果进行了验证,证明了方法的有效性。
An analytical solution based on eigenfunction and matching method is developed for the interaction of oblique waves with infinite number of double-layered perforated caissons with transverse wall. According to the division of structures, the whole fluid domain is divided into infinite sub-domains firstly, and eigenfunction expansion is used for representing the velocity potential in each domain. A phase relation is utilized for analyzing the wave motion in each caisson, and the structure geometry character is considered in setting up the mathematical model of reflected waves. At last, the present analytical solution is validated by comparing the numerical predictions with experiment results.
