摘　　要：内孤立波是海洋、近岸、河口等水体中常见的物理现象,在稳定层化水体中的密度跃层上由外界扰动诱发产生,其传播过程中所激发的剪切流会伴随着巨大的能量,对水下工程结构物的安全稳定造成严重威胁。因此,探究内孤立波与工程结构物相互作用规律具有重要意义。在整理与总结国内外众多学者研究进展的基础上,从物理试验与数值模拟2个方面介绍了内孤立波对结构物作用特性研究的常见方法,并对竖直柱状物在内孤立波环境下所受水平作用力、垂向作用力与力矩特性规律和所受水平作用力敏感性因素的研究成果进行总结。最后,对内孤立波环境下竖直柱状物受力特性相关研究后续需要关注的问题进行展望。Internal solitary waves represent a common physical phenomenon in water bodies such as oceans,coasts,and estuaries.They are induced by external disturbances on a pycnocline in a stably stratified water body,and the shear flow excited during their propagation is accompanied by huge energy,which poses a serious threat to the safety and stability of underwater engineering structures.Therefore,it is of great significance to explore the laws of interaction between internal solitary waves and engineering structures.On the basis of summarizing the research progress of many scholars both at home and abroad,the common methods for studies on the action characteristics of internal solitary waves on structures are introduced from the aspects of physical experiments and numerical simulations.In addition,this study gives a summary of the research results in the characteristics and laws of the horizontal force,vertical force,and moment on vertical cylinders under internal solitary waves and the sensitivity factors of the horizontal force.Finally,the issues that require further attention in follow-up research on mechanical characteristics of vertical columns umder internal solitary waves are raised.
