In recent years, many accidents occurred in the operation of pipe corridors at home and abroad. Especially with the entrance of power cables, gas and thermal pipelines, the risk factors of the pipe corridors were greatly increased. Pipeline damage and operators suffered injuries and deaths caused by electromagnetic interference of the pipeline in the corridor were the most important safety hazards for the safe operation of urban underground comprehensive corridors. In order to find out the influencing factors and laws of electromagnetic interference of high voltage transmission lines in the pipe corridor, and to provide technical support for the construction of corridors, the professional analysis software CDEGS was used to simulate the influence of the high voltage transmission lines in the corridor on the electromagnetic interference of the pipeline in the corridor. Results showed that the induced voltage and induced current on the pipeline increased with the increase of high voltage line voltage and soil resistivity, and firstly decreased rapidly and then slowly decreased with the increase of the distance between the pipeline and the high voltage line. The pipeline specifications had little effect on the induced voltage and induced current. As the resistivity of anti-corrosion layer increased, the induced voltage first increased and then tended to be stable, whereas the induced current decreased first and then tended to be stable.
