摘要
采用专用回流轨(第四轨)方式,可以有效解决杂散电流问题,但是国内地铁工程却从未采用过此方案。本文通过对国外地铁四轨方案的调研,结合国内类似工程案例,对地铁工程的四轨回流系统进行了可行性研究,分析了优缺点,提出了四轨系统的适用条件。
The special return rail(fourth rail)method can effectively solve the stray current problem,but the domestic subway project has never used this scheme.This paper analyzes the advantages and disadvantages of the four-track scheme of foreign subways and combines similar domestic engineering cases.The feasibility study of the four-track recirculation system of the subway engineering is carried out,and the applicable conditions of the four-track system are proposed.
