摘　　要：中国桥梁建设数量多,规模大。桥梁处于大气环境中,会受到环境作用而腐蚀破坏,如不加以防护,会影响结构物的安全和使用寿命,防腐蚀涂料可以起到防护作用以延长桥梁的耐久性,文章通过对国内外桥梁防腐蚀涂料使用案例的综述,以及国内外标准规范中对大气区防护方案推荐的总结,得出耐久性优异的新材料已在行业标准规范中得到体现,近期建设的大型桥梁均采用技术先进和耐久性好的防腐蚀涂料体系,说明中国的桥梁防腐蚀涂装已经与世界先进国家同步发展。The numbers and size of bridge construction are high in China. The safety and durability of bridges may be affected without protection, due to the corrosion of steel structure of bridges exposured in atmospheric zone. Anticorrosion coatings can provide protection and prolong the durability of bridges. This paper reviewed the current status of anti - corrosion coatings applied on bridges in the world, and the protective ways of steel bridges in atmospheric zone recommended in domestic and foreign standards. It was concluded that those advanced and durable materials were specified in the standards and applied on several new large bridges in China. The results indicated that the development of anti - corrosion coatings for bridges in China are at the same level as that in advanced countries.
