摘　　要：地铁作为我国城市轨道交通体系的骨干,在技术上和经济上均有明显的优越性,随着社会的发展,城市道路交通的压力突飞猛进,地铁建设与使用需求将越来越大。但地铁却有因杂散电流泄漏而造成严重腐蚀的问题。本文针对这一现状阐述了杂散电流的腐蚀机理与估算方法,并详细地对现有的各种杂散电流防护方法进行了学习研究,全面分析对比之后得出了一些总结和个人设想,总结出了一些对杂散电流防护有用的结论,并提出了一些对杂散电流防护有用的建议与策略。As China＇s urban subway rail system, the backbone of the technical and economic superiority are obvious, as the society develops, more and more popular subway. But this one is hidden as a result of stray current leakage caused by severe corrosion problems. This article discusses the status of the stray current corrosion mechanism and methods to estimate and detail of the existing methods of stray current protection for a comprehensive and detailed summary of the analysis and synthesis, and then arrive at a number of stray current Protection useful conclusiens, the last of a number of stray current protection strategies and useful suggestions.
