摘　　要：杂散电流腐蚀对城市轨道交通建筑主体结构会产生很大的危害,造成工程上的安全隐患,因此,应在工程设计和施工中给予高度重视。从电腐蚀原理、杂散电流成因、杂散电流简易计算分析,以及杂散电流防护等方面进行阐述,分析杂散电流的防护方向和相关防护措施,以供其它城市轨道交通项目参考。Stray current corrosion is an inevitable problem of the tractive power supply system in urban rail transit.This electric rot,which could cause great damage to the major structure of rail transit and bring about potential safety concerns on engineering,should be attached with much importance in design and construction of the rail transit engineering.This paper presents the principle of electro corrosion,the formation of stray current,the simple computational analysis on stray current and the protection against stray current,attempts to make an objective analysis of the protective orientation and measures against stray current for other urban rail transit items.
