长沙湾大桥立柱耐久性加固与综合防腐技术

长沙湾大桥是一座跨海湾大桥，受海洋腐蚀性气候的影响较大，许多立柱都出现了混凝土保护层整层剥落、钢筋严重锈蚀等病害。针对该桥的病害，采用了多种技术措施对其进行处理，包括干轧混凝土及环氧混凝土修补缺陷、涂刷迁移渗透型阻锈剂、外包高性能混凝土、粘贴高强玻璃纤维布、防腐油漆涂装等技术。文中主要介绍这些技术措施的工作原理、施工工艺等，为同类工程提供参考。

The Durable Reinforcement and Comprehensive Anti-corrosion Technology of Column in Changsha Gulf Bridge

Changsha Gulf Bridge is a cross-bay bridge,in which a number of concrete columns appeared such diseases as entire peeling of protective concrete layers and serious corrosion of steels because of the ocean's corrosive climate.Thus,a variety of technical measures were used to deal with the diseases mentioned above,which include using dry rolling concrete and epoxy concrete to repair defects,brushing migration-infiltration inhibitor,warping the old columns with high-performance concrete,pasting high-strength g...
