摘　　要：随着全球极端风浪天气日益增多,已建港口防波堤受损的情况逐年增加。为分析总结防波堤受损机理和修复领域的研究成果,收集近年来国内外34个防波堤损坏和修复案例,总结出斜坡堤损坏的4种主要因素并选取典型案例进行介绍,提出斜坡堤的修复和新建设计的合理化建议。对于外侧护面结构破损严重的斜坡堤,建议将已有结构作为堤心,新建护面结构进行修复;对于浪高和地形复杂的新建工程,建议综合考虑含建设费用和维护费用的全生命周期费用,充分考虑斜坡堤维护和修复的便利性,合理选取断面形式并采用块体强健性高、易修复的人工块体。With the growth of global extreme stormy weather,the damaged breakwaters of built ports have increased year by year.To summarize the research results in the field of breakwater damage mechanism and repair,thirty-four cases of domestic and foreign breakwaters damaged in recent years are collected in this paper.The four main factors that cause damage to sloping breakwater are summarized.Typical cases for each factor are introduced to propose reasonable suggestions for sloping breakwater repair and design.For a sloping breakwater with severe damage to the outer protective structure,it is recommended to use the existing structure as the core and construct a new protective armor structure for repair.For new projects with high wave heights and complex terrain,it is advisable to consider the life-cycle cost,including construction and maintenance expenses,and carefully consider the convenience of maintenance and repair.It is recommended to select a suitable cross-sectional form and artificial blocks with high robustness and ease of repair.
