摘　　要：随着高压交流输电线路、交流电气化铁路及油气管道的迅速发展,油气管道不可避免地与其交叉或平行,甚至共用走廊,管道遭受的交流干扰影响日益严重。对于已建管道,受到严重交流干扰,但不能确定准确干扰源时,如何有效设计缓解措施是较为困难的。为此,通过测量埋地管道的稳态持续交流干扰电压,然后采用计算机软件模拟交流干扰结果,进而设计缓解措施,提出缓解措施的具体技术指标,如接地位置、接地规模、接地电阻等。结果表明:计算机软件可模拟交流干扰电压分布,并有效设计缓解措施方案。With the rapid development of high-voltage power transmission lines, AC electrified railway and oil and gas pipeline are suffering from AC interference increasingly. When existing pipeline are subjected to serious interference but an accurate source of interference cannot be determined, it is more difficult to design effective mitigation measures. Through measuring the continued AC interference voltage in the stable state of buried pipeline, effective mitigation measures through simulating AC interference results with computer sottware can be designed and determined to propose specific technical indicators for mitigation measures, such as earthing position, earthing scale, earthing resistance, etc. Research results show that computer software can simulate AC interference voltage distribution on the pipeline and design effective mitigation measures. （3 Tables, 5 Figures, 6 References）
