摘　　要：浮式防波堤是一类布置在近海区域或浅水流域的重要海洋工程结构物,主要作用是避免从远海传播的波浪对其附近水域内的船舶或其他浮式结构物的安全作业环境构成威胁,提供一个较为平稳的区域水体环境。文章使用光滑粒子流体动力学(Smoothed Particle Hydrodynamics,SPH)方法,基于悬链线方程理论,开展浮式防波堤与系泊系统耦合水动力数值分析方法的研究。基于流固耦合理论,编写SPH计算程序,数值求解浮式防波堤在不同波浪载荷下的运动特征,分析影响防波堤消波特性的主要因素。Floating breakwaters are important offshore structures,which are applied to offshore areas or in shallow watersheds.They are mainly used to avoid threats to the working conditions of vessels or other floating structures in nearby waters and provide a more stable regional water environment when waves spreading from the abysmal sea.A Smoothed Particle Hydrodynamics(SPH)method is employed to develop a numerical method for the coupled hydrodynamic analysis between floating breakwaters and mooring systems based on the theory of catenary equations in this paper.SPH calculation program is compiled which is based on fluid-structure interaction mechanics theory.The program can help realize numerical solution to the motion characteristics of floating breakwaters under different wave loads.The main factors affecting the wave attenuating characteristics of floating breakwaters are analyzed.
