摘　　要：[目的]目前,我国数个城市开始规划25 kV交流供电制式地铁线路,不可避免地会有油气管道与地铁隧道并行区段,地铁运行期间的交流干扰易造成油气管道发生电解腐蚀,从而造成安全事故,为了地铁与油气管道的安全运行,需对交流牵引的地铁隧道与油气管道间的耦合作用进行研究。[方法]使用CEDGS接地仿真计算软件对隧道进行仿真建模,研究不同方法施工的隧道对油气管道交流干扰的影响规律。[结果及结论]仿真研究结果发现:矿山法施工的隧道对油气管道的交流干扰抑制效果要高于盾构法施工的隧道;油气管道首末端感应电压压差主要和其与接触网位置耦合关系有关;油气管道涂层耐受电压受地表电位和管道感应电压的双重影响。[Objective]Currently,several cities in China are planning 25 kV AC(alternating current)power supply metro lines,inevitably there will be paralled sections of oillgas pipelines run parallel to metro tunnels.During metro operation,AC interference can lead to electrolytic corrosion of oil and gas pipelines,potentially causing safety incidents.To ensure the safe operation of both metro systems and pipelines,it is necessary to study the coupling effects between AC-powered metro tunnels and oil and gas pipelines.[Method]The CDEGS grounding simulation software is used to model metro tunnels and analyzed the impact of different tunnel construction methods on AC interference in oil/gas pipelines.[Result&Conclusion]Simulation results indicate the following:tunnels constructed using the mining method exhibit superior suppression of AC interference in oil and gas pipelines compared to those constructed using the shield tunneling method;the induced voltage difference at both ends of the pipelines primarily depends on their coupling relationship with the catenary network location;and the withstand voltage of pipeline coatings is influenced by both the surface potential and the induced voltage on the pipeline.
