摘　　要：内孤立波广泛存在于密度层化的海洋中,是一种常见的非线性、大振幅的波动现象。在其传播过程中会诱导波面上下的海水流动呈现剪切状态,并引起海水强烈的幅聚幅散和突发性的强流。当运动潜体在水下作业时极有可能会遭遇内孤立波,内孤立波峰高谷深、能量集中,严重影响到潜体的运动稳定性和水动力载荷特性,进而导致潜体运动失稳、操纵失控等。首先,基于海洋内孤立波与潜体相互作用这一工程背景,从理论研究、观测与试验研究及数值模拟研究3个研究方向总结当前国内外关于内孤立波特性的研究;然后,分别对内孤立波与结构物相互作用、内孤立波与潜体相互作用的研究予以总结;最后,基于现阶段国内外关于内孤立波的研究现状,进一步提出内孤立波研究的工作展望。Internal solitary waves(ISWs)are a common nonlinear,large-amplitude fluctuation phenomenon which is widely present in densely stratified oceans and can induce the shear state of the seawater flow above and below the wave surface during the propagation process,causing strong amplitude dispersion and the sudden strong flow of seawater.When a moving submersible operates underwater,it is very likely to encounter ISWs.The motion stability and hydrodynamic load characteristics of the submersible are seriously affected by the peak and valley depths and energy concentrations of ISWs,which in turn leads to its unstable motion and uncontrolled maneuvering.Based on the engineering background of the interaction between ISWs in the ocean and underwater submersibles,this paper summarizes current research on the characteristics of ISWs in terms of theory,numerical simulation and observation and experiment.Studies on the interaction between ISWs and marine structures and submersibles are then highlighted.Finally,based on the current status of ISW research at home and abroad,the future prospects of ISW research are further proposed.
