摘要
钢筋腐蚀可能使钢筋混凝土结构不耐久.目前使用的大量结构,主要由于钢筋腐蚀,其更换速度和修补所需要的费用是惊人的。笔者根据我国海港工程钢筋混凝土结构(以湛江港一区老码头为例)和北美洒除冰盐的钢筋混凝土公路桥面板的腐蚀破坏情况、防腐经验和经济分析,就我国海港钢筋混凝土结构防腐决策提出建议。
Reinforced concrete structures may be undurable by steel corrosion in concrete. Chiefly due to the corrosion problem, the large amounts of part replacement frequency and maintenance charge for a large number of existing structures are staggering. Based on the corrosion condition, anticorrosion experiences and cost analysis of Zhanjiang-Gang harbour structures as an example in China, as well as these of concrete bridge desks in deicing environment in North America, recommendations on the anticorrosion decision of marine reinforced concrete structures in China were presented.
