摘　　要：目前,对轨道交通动态杂散电流干扰原理的研究开展的很多,但是,如何判断干扰电流对在役埋地燃气管道的危害程度,至今国内外还没有非常有效的手段。因此,比较了几种测试方法的适应性,提出了管地电位波动监测与SCM杂散电流检测仪相结合的检测方法,为埋地燃气钢质管道周围环境的杂散电流干扰测试与评价提供了新的依据。Up to now, the interference principle of rail traffic stray current has been researched clearly, but a very effective method has not been found to judge the degree of damage by the interference current. Therefore ,several methods are compared and a synthetic method--the pipe-to-soil potential sequential fluctuation monitoring and stray current detection by using SCM is brought forward ,which provides new evidence to buried gas pipeline stray current detection and evaluation.
