摘要：
Stray current will leak due to rail insulation reduction in urban metro system with direct current traction. As a result, adjacent buried pipeline and its sacrificial anode cathodic protection system will be interfered to threat the safety operation of pipeline and cathodic protection system. Numerical simulation technology was used to calculate and solve such interference problems, which was verified using the existing literature data. Meanwhile, actual case calculation was performed to analyze the influence laws of metro stray current on buried pipeline cathodic protection level and sacrificial anode output. Aiming at the obtained influence laws, the corresponding protection methods were proposed, and its effectiveness was also analyzed. The research results can provide references for buried pipeline protection design from metro stray current interference. © 2016, Science Press. All right reserved.
