聚焦波作为一种模拟极端波浪的有效手段，其常常被用于极端波浪下海洋结构物的动力响应模拟中，然而在数值水池中产生聚焦波时，如何有效抑制反射波，对于聚焦波的模拟结果至关重要。本文基于STAR-CCM+软件建立数值波浪水池，进行聚焦波模拟，针对应用于水池消波的2种消波方法（力消波法和阻尼消波法）进行考察，分析相应消波方法的相关参数对于反射波消波结果的影响。基于水池中监测点所测量的波面时历结果及其波分量幅值谱和本文所定义的误差指标Er，考察获得相应消波方法中不同参数的最佳取值。所得研究结果可为聚焦波的有效模拟及其作用下海洋结构物的水动力响应数值研究提供参考。
Focused waves, as an effective method of modeling extreme waves, are often used in simulation of the dynamic response of marine structures under extreme waves, however, when generating focused waves in a numerical tank, how to effectively suppress reflected waves is critical to the simulation results of focused waves. A numerical tank is established based on the STAR-CCM+ software for focused wave simulation, and two methods (wave forcing method and damping zone method) used to absorb reflected waves in the tank are examined separately. The effect of different parameters of corresponding methods are analyzed on the absorption results of reflected waves. Based on the time history of wave free surface results measured at the monitoring point in the tank and its wave components amplitude spectrum and the error index Er, the optimized values of corresponding parameters for their wave absorbing methods are obtained. These obtained results can be used as a reference for numerically modelling the hydrodynamic response of marine structures under extreme waves.
