城轨交通隧道过江段杂散电流防护方案探讨

摘要

简介城市轨道交通工程中杂散电流防护的基本原理，并分析过江隧道区段的特点，同时对过江隧道区段杂散电流防护的不同方案进行了比较分析，提出了可行的过江隧道区段杂散电流防护方案及优化建议，并对目前城市轨道交通过江隧道区段杂散电流防护方案进行了较为深入的总结。%The paper introduces the basic principles of stray current protection in transit projects, and analyzes the characteristics of cross-river tunnel, while a comparative analysis of different schemes for stray current protections in cross-river tunnel is made. It proposes feasible protection schemes and optimization recommendations for stray current in cross-river tunnel, and makes a more in-depth summary on protection schemes for stray current in cross-river tunnel of existing transit.
