摘　　要：近场动力学作为一种非局部理论,能够通过键的失效来自发模拟材料的失效、破坏,其在海洋工程领域已取得初步的研究成果,尤其是在冰区船舶与海洋工程领域,更显出了该方法的优越性。为了更好地了解近场动力学在冰区船舶和海洋工程中的应用,对近场动力学在冰区船舶与海洋工程应用中的问题进行梳理,主要包括冰材料本构模型、冰−结构作用模型、冰−水耦合方法、结构物力学模型、水下爆炸破冰应用及结构表面覆冰除冰的应用等。同时,在全面回顾已有研究成果的基础上,分析其特点和面临的挑战,探讨相应的解决思路和未来的研究方向。As a non-local theory,peridynamics can spontaneously simulate material failure and damage through bond failure.It has achieved preliminary research results in the ocean engineering sector,especially in the field of ships and marine structures in ice zones.In order to better understand the application of peridynam-ics to ships and marine structures in such environments,this paper presents relevant applications including the ice constitutive model,ice-structure interaction model,ice-water coupling method,structural mechanics mod-el,application of icebreaking through underwater explosion,application of structure surface deicing,etc.Fi-nally,an attempt is made to comprehensively review the existing published research,analyze its characterist-ics and challenges,and provide corresponding solutions and future research directions.
