摘　　要：文中主要研究了电气化铁路对埋地钢质燃气管道交流干扰的影响。在京沪高铁试运行期间选取了9条管线进行普测,证实了整个京沪高铁沿线的管线确实受到了交流干扰。通过测试交流电气化铁路在试运行、正式开通后交流干扰的变化情况,表明高铁发车密度越大、载重量越重,所产生的交流干扰明显加大。同时,通过对施加排流措施前、施加排流措施后的对比测试,发现通过增加排流措施,可以使管道受到的干扰大幅度降低,证明了排流工程的有效性。This paper mainly studies AC interference of electrified railways on the buried gas pipelines.The tester selected nine pipelines on the Beijing-Shanghai high-speed rails during the trial run for a general survey,and the result confirms that the pipelines along the Beijing-Shanghai high-speed rail are affected by AC interference.By testing AC electrified railway test run,the official opening of the AC interference indicates that,for the high-speed rail on the grids,the greater the density,the heavier the load,the AC interference increased much more.With drainage measures imposed before and after comparison tests,testers found that by strengthening the drainage measures the interference of the pipeline can be reduced by a significant margin.This proves the effectiveness of the measures.
