摘　　要：随着我国长输管道及各类地下管道铺设里程的不断增长,由杂散电流引起的管道腐蚀问题越来越被人们所关注。基于国内外杂散电流的研究成果,分析了杂散电流的腐蚀机理,总结了杂散电流产生的主要原因,简单介绍了杂散电流的特点及其腐蚀危害性,并通过事例分析了目前杂散电流常用的工程测试方法及防护策略。With the increase of built long-distance pipelines and other buried pipelines, the stray current corrosion of buried pipelines has received increasing attention. Based on the references and documents published in relevant fields, the stray current corrosion mechanism is analyzed, its main causes are summarized, the characters and harmfulness of stray current corrosion are introduced, some examples are given to analyze the engineering testing method and protection strategy about stray current corrosion.
