| 摘 要： | 钢筋的腐蚀对钢筋混凝土结构的使用寿命影响极大,外加电流阴极保护系统能较好地控制钢筋锈蚀,尤其适用于沿海地区受氯盐侵蚀所引起的钢筋腐蚀,本工作重点介绍了在沙特波斯湾沿海一座混凝土结构中所采用的外加电流阴极保护情况,以位于取水口和排水口的阴极保护分区为研究对象,在工场现场对保护电流进行了研究,并对相关的技术参数进行了分析。结果显示,在中东严酷海洋腐蚀环境中的钢筋混凝土结构,外加电流阴极保护系统给混凝土结构提供相对于钢筋表面电流密度大小为5mA/m2的保护最为合适。

| Abstract: | Corrosion of rebar in concrete structure affect its service life greatly,by the impressed current cathodic protection(ICCP) system can solve this problem,especially for the reinforced concrete corrosion caused by chloride ion in coastal areas.The ICCP system which installed in a concrete structure of the coast of Persian Gulf Saudi Arabia was introduced,and the protection current density was studied.The results showed that in the severe corrosive environment such as the coast areas of Middle East,a current density of 5 mA/m2 was suggested to provide protection for the rebar in concrete structures by the ICCP system |
