利用48 h远传监测、24 h扁铁对地电位测试、现场埋片试验以及实验室模拟试验等评估了中低速磁悬浮列车对某埋地管道的电磁干扰情况。结果表明：磁悬浮轨道与管道交叉点或远离点处的通电电位相差较小；磁悬浮高架桥墩处接地扁铁对地电位基本为-0.68 V，随着磁悬浮列车的经过，扁铁对地的电位值并没有明显的正向偏移。埋设在不同位置试片的腐蚀形貌和腐蚀速率相差较小，磁悬浮对某埋地管道的电场和磁场干扰较小。

The electromagnetic interference of low and medium speed maglev train on a buried pipeline was evaluated using 48 hour remote transmission monitoring, 24 h flat iron-to-ground potential test, field buried test and laboratory simulation test. The results show that the difference between the on-potentials at the intersections or distant points of the magnetic levitation orbit and pipeline was small. At the pier of magnetic levitation viaduct, the potential of the ground flat iron to ground was about -0.68 V. With the passage of the magnetic levitation train, the potential of the flat iron to the ground did not shift significantly. The difference of both corrosion morphology and corrosion rates of test specimens buried in different positions were relatively small, and magnetic levitation had little interference on the electric and magnetic fields of the buried pipeline.
