摘要
分别从动态直流杂散电流干扰的腐蚀规律、机理研究以及腐蚀评判标准方面,介绍了国内外轨道交通对埋地管道动态直流杂散电流干扰的研究现状和进展,并对动态直流杂散电流干扰腐蚀的相关研究方向提出展望。
With the rapid development of energy-and transport-industry, it happens often in the practice that the urban rail transit and the buried pipeline system may intersect or parallel with each other.Therefore, the dynamic DC stray current of the urban rail transit interferes with the buried pipeline more and more seriously. The paper introduced the following aspects related with the effect of dynamic DC stray current on the pipeline： namely the regularity and mechanism of pipeline corrosion induced by the stray current, the judgment standard for evaluating corrosion risk, and the research status and research progress on dynamic DC interference of urban rail transit on the buried pipeline. At last, the research trend on the effect of the dynamic DC stray current interference was discussed.
