摘要

在极地海冰覆盖区域，冰水界面波动的回复力除重力外，还需考虑冰层的弹性力，这种波动被称为水弹性波（或挠曲重力波）。与海洋表面波浪不同，水弹性波的传播特性不仅受到流体动力学控制，还显著依赖于冰层的弹性力学特征，其临界共振体系完全不同于纯重力水波，在临界速度附近表现出独特的非线性波动现象。本文系统综述了移动载荷激发水弹性波的研究进展，涵盖理论模型、数值计算与实验观测，重点探讨了势流模型、黏弹性效应、非线性效应以及复杂运动场景（如变速运动、三维效应、渠道边界和水下载荷等）下的冰层动力学特征，发现黏弹性和非线性效应是解释临界速度下有限振幅响应的关键机制，复杂运动场景中的水弹性波传播特性则进一步揭示了冰-水耦合作用的多样性。本文研究可为极地资源开发、船舶航行安全、海洋超大浮体结构设计提供重要的理论支撑和技术参考。

Abstract

In polar ice-covered regions

wave motion at the ice-water interface is governed by a restoring force comprising both gravity and the elastic force of the ice layer. Such waves are known as hydroelastic waves (or flexural-gravity waves). Unlike ocean surface waves

the propagation characteristics of hydroelastic waves are governed not only by hydrodynamics but also significantly depend on the elastic properties of the ice layer. Its critical resonance regime differs entirely from pure gravity waves

exhibiting unique nonlinear wave phenomena near the critical velocity. This paper systematically reviews research progress on hydroelastic waves excited by moving loads

covering theoretical studies

numerical simulations

and experimental observations. Key aspects include potential flow models

viscoelastic effects

nonlinear dynamics

and ice sheet dynamic characteristics under complex motion scenarios (such as accelerated motion

3D effects

channel boundaries

and submerged loads). The study reveals that viscoelastic and nonlinear effects are key mechanisms explaining the finite-amplitude response at critical velocities

while the propagation characteristics of hydroelastic waves in complex motion scenarios further demonstrate the diversity of ice-water coupling interactions. This paper provides critical theoretical and technical insights for polar resource exploitation

ship navigation safety

and the design of large-scale floating marine structures.
