地铁杂散电流的腐蚀及防护影响分析

Subway Stray Current Corrosion and Protection

根据轨道交通的杂散电流产生原理,结合工程实际,提出了杂散电流防护体系;并结合轨道交通的工程特点,从杂散电流与接地的关系分析,提出了隧道和车站的结构钢筋可用作设备接地的建议。

According to the principle of the stray current occured in rail transit, this paper proposes an intact stray current protection system, of combined with the project characteristics of the rail transit. By analysing the relation between the stray current and the grounding, the auothor argues that the structural reinforcing bar in tunnel and station can be used as the grounded equipment.
