利用完全非线性Boussinesq模式FUNWAVE 2.0模拟了垂直入射双色短波群引起的近岸礁石附近细长矩形港内的亚重力周期振荡。本文基于IG波分离方法，系统地研究了在2 ~ 5阶振型条件下，最大IG周期分量振幅、自由IG波和束缚IG波及其相关分量在港内随礁面平面坡度和入射短波振幅的变化规律。对于给定的港池、礁面坡度和入射短波振幅的范围，研究表明，港池内最大IG周期分量振幅和自由IG分量振幅随礁面坡度的变化幅度较大，且随礁面坡度的变化趋势基本一致，而港内的束缚IG波对其不敏感，其最大IG周期分量幅值以及港内束缚和自由IG驻波的最大IG周期分量幅值均随入射短波幅值的三次方变化。
The infragravity (IG) period oscillations inside an elongated rectangular harbor near the offshore fringing reef induced by normal-incident bichromatic short wave groups are simulated using a fully nonlinear Boussinesq model, FUNWAVE 2.0. Based on an IG wave separation procedure, this article presents a systematical investigation on how the maximum IG period component amplitude, the bound and free IG waves, and their relative components inside the harbor change with respect to the plane reef-face slope and the incident short wave amplitude under the condition of the 2nd to the 5th modes. For the given harbor and the ranges of the reef-face slope and the incident short wave amplitude studied in this paper, it is shown that both the maximum IG period component amplitude and the free IG wave component amplitude inside the harbor fluctuate widely with the reef-face slope, and their changing trends with the reef-face slope are almost identical with each other, while the bound IG waves inside the harbor seem insensitive to it. Both the maximum IG period component amplitude and those of the bound and free IG standing waves inside the harbor change cubically with the incident short wave amplitude.
