摘　　要：针对是否全面提高港口工程结构设计使用年限的问题,回顾目前我国港口工程结构设计使用年限确定的过程,对比分析国内外工程结构设计使用年限的规定,总结国内外设计使用年限100 a时的设计规定,分析提高港口工程设计使用年限需考虑的因素,讨论提高设计使用年限需开展的工作。研究认为,全面提高港口工程结构设计使用年限在技术上是可行的,但需要开展作用取值、结构可靠度分析、耐久性设计方法等多方面研究工作。参考国内其他行业和国外港口工程结构设计使用年限规定,结合我国港口使用现状,提出永久性港口建筑物设计使用年限仍采用50 a,对于特别重要的港口工程,可结合业主要求,采用50 a以上的建议。This paper reviews the process of determining the design working life of port engineering structure in China at present,compares and analyzes the regulations for the design working life of the domestic engineering structure and foreign port engineering structure,summarizes the design regulations of domestic and foreign structures with a design service life of 100 years,analyzes the factors to be considered in increasing the design working life of the port engineering structure,and discusses the work to be carried out to improve the design working life.The research shows that it is technically feasible to improve the design working life,but it is necessary to carry out research work on the value of action,structural reliability analysis,durability design method,etc.Referring to the regulations on the design working life of other domestic industries and foreign port engineering structures,and considering the current situation of port use in China,it is proposed that the design working life of permanent port buildings should still be 50 years,while it can be more than 50 years according to the requirements of owners for particularly important port projects.
