摘　　要：本文介绍了杂散电流的产生、类型及腐蚀作用机理。根据北京市城市轨道交通发展现状,选取地铁附近燃气管段,进行某点的埋地钢质燃气管道杂散电流干扰调查和测试。通过对检测结果进行分析,认为地铁杂散电流对燃气管道的影响不可忽视,并提出了杂散电流腐蚀防护的措施。This paper introduces the generation,type and mechanism of stray current.According to the development status of urban rail transit in Beijing,the gas pipe section near the subway is selected to investigate and test the stray current interference of buried steel gas pipeline at certain point.Results show that the effects of stray current on gas pipeline cannot be ignored,and the protectionmeasures of stray current corrosion are also put forward.
