摘　　要：针对高压输电线工频电磁场产生的交流电压引起附近埋地管道的交流腐蚀,进而影响管道服役寿命的问题,开展了高压线对埋地管道耦合干扰规律的试验研究。设计并建立了室内试验装置,通过试验研究分析了输电线电压、电流、高度等因素对管道感应电压的影响,为总结干扰规律、研究管道腐蚀机理提供了试验依据。Alternating voltage from the power frequency electromagnetic field of high-voltage transmission line will lead to AC corrosion of buried pipeline near the line, then shorten the service life of the pipeline. In the light of this problem, experimental study on coupling interference law of high-voltage transmission line on buried pipeline is carried out. Laboratory test devices are designed and established. Influence of voltage, current and height of power transmission line on induced voltage of pipeline is analyzed through experimental study, which can provide test foundation for summarizing interference law and research on corrosion mechanism of pipelines.
