摘　　要：冰工程对于断裂力学是一个相对较新的应用领域.对不同工程领域中广泛存在的涉冰断裂力学问题进行了列举归纳,然后从冰的自然特性诸方面论证了冰工程分析中引入断裂力学方法的必要性及其适用性,最后综述了主要的研究成果和进展.Ice engineering is a relatively newer field for applications of fracture mechanics. In this paper, firstly, some prevalent subjects of ice fracture mechanics, which exist widely in different engineering fields, are enumerated and inducted. And then, from various aspects such as ice properties etc., the necessary and adequate of adopting the approach and viewpoint of fracture mechanics to analyze some ice engineering problems are demonstrated. In final portion, some important research achievements and tendency are summarized. 145 references are quoted in the review.
