摘　　要：全球性气候变暖的持续使极地科学成为国际科研热点.极地声学技术研究在近年国内学者的努力下取得了长足进展,但在基础理论研究方面还有很多需要攻坚的难题.极地冰声传播受弹性波导影响严重,特殊的材料物理特性、复杂的边界条件以及极端恶劣的环境均给相关研究推进带来挑战.针对冰声波导模型精细化构建难题,本文从海冰物理特性概述、冰声传播理论模型构建、冰声传播特征方程数值求解以及冰声参数评估与选取四个方向出发,回顾并梳理了极地海冰声波导建模关键技术的发展历程与研究现状,分析了国内外冰声传播研究进展,讨论并展望了冰声波导建模技术的未来研究重点以及其在极地开发中的应用潜力,以期为后续极地声学理论与应用研究的开展提供有益参考.With the continued global warming,polar science has become one of the research hotspots.Regarding polar acoustics,much progress has been made due to the efforts made by scientists in the world.With the enhancement of stereoscopic monitoring capacity in polar regions,the acoustic theory and technologies applicable to Arctic sea-ice,which have long been overlooked as a branch of acoustics,are now dawning more and more attention.The propagation of elastic waves in the Arctic sea-ice is governed by its waveguide,and the understanding of which faces a grave challenge due to the unique material properties and complex internal structure of sea-ice,along with the asymmetric fluid-solid coupling at its boundaries and the inaccessibility for in-situ experiments,which is caused by the extreme condition.Aiming at an effectively and precisely modeling technique of acoustic propagation in sea-ice,including its waveguide,in this paper,the progress,the development,and the status of corresponding researches are reviewed.For a better understanding of the modeling of sea-ice,Arctic sea-ice,i.e.its formation condition,geometries,mechanical properties,microstructures,and the acoustic propagation,is briefly introduced.Different approaches to modeling the propagation of elastic waves in ice-floe based on explicit/implicit boundary conditions are presented and explained in detail.The resulting transcendental characteristic equation describing the acoustic propagation needs to be solved in a complex space for the severe energy leakage at the water-ice interface,and the necessary numerical methods of solving this equation are then explained and compared with each other.Since accurate parameters are imperative in having a satisfactory fidelity for any physical model,the acoustic parameters of Arctic sea-ice,historical evolution and experimental results,along with its assessment techniques are also presented,and a set of sound velocity parameters of Arctic sea-ice are provided for modeling.The roughness of the ice-water interface is discuss
