摘　　要：模拟地铁的实际工况,使用长效铜/硫酸铜电极作为测量混凝土钢筋极化电位的参考电极,检验长效铜/硫酸铜电极的稳定性、有杂散电流扰动时混凝土钢筋极化电位的变化情况以及参考电极安装位置的不同对极化电位测量的影响,同时根据广州地铁一号线杂散电流监测系统记录的数据,分析长效铜/硫酸铜电极的工作情况.实验证明,长效铜/硫酸铜电极可以在地铁的混凝土结构中用于测量埋地金属结构的杂散电流腐蚀.By simulating metro actual conditions, along effect copper or bluestone electrode was used as reference electrode of measuring concrete steel bar polarity voltage. Bluestone electrode's stability and reaction of polarity voltage to stray current disturbing and influence of different fixed positions on measuring polarity voltage were testified. On the basis of data from stray current monitoring system in Guangzhou Metro Line No.1, the bluestone electrode working condition was analyzed. Experiment shows that the long effect copper electrode can be used as measuring stray current corrosion on buried metal structure in metro concrete structure.
