摘要
通过室内试验,针对大气区被氯盐污染的钢筋混凝土采用外加电流阴极保护系统其阴极保护电流在被氯盐污染混凝土结构的多层钢筋的分布规律进行了研究,为混凝土外加电流阴极保护工程的设计提供指导。研究结果表明:在大气区被氯盐污染混凝土中,邻近辅助阳极的第1和第2层钢筋共吸收的的电流较多,占总电流的70%以上;第2层钢筋与第1层钢筋的间距对电流在的钢筋中的分散情况影响较大。
This paper studies the protection current distribution of impressed current cathodic protection（ICCP） for chloride contaminated reinforced concrete in the atmosphere zone.It seeks to master the main technical parameters of ICCP and applied to practical engineering.The layers and spacing of electrical connection steel rebar effect on the current distribution have studied in this paper.The results indicate that for the ICCP system which is applied to the chloride contaminated concrete of atmosphere zone,the first and second layers of reinforcement adjacent to the auxiliary anode absorbe more than 70% of total current,and their spacing has a great impact on the current dispersion in the steel reinforced bars.
