摘　　要：滨海环境下钢筋混凝土桥梁结构的耐久性是受到广泛关注的问题,本文以江苏省临海高等级公路连云港段某大型桥梁工程为例,从原材料控制指标、配合比、设计强度等级与保护层厚度以及耐久性附加措施等几个方面,对滨海环境下桥梁混凝土结构方案进行了优化设计。Corrosion damage of reinforced concrete bridge structure in coastal area was widely paid attention over the world.Taking one bridge built in Jiangsu coastal high-grade highway in Lianyungang Distriction as an example, a durability optimum design of concrete construction,including quality control of raw materials,mix proportion,designed strength grade,cover thickness and additional measures were researched in this paper.
