摘　　要：为了保障城市轨道交通的安全,对腐蚀轨道附近建筑中钢筋的杂散电流的检测和防护已成为必然。复杂的环境使杂散电流难于直接检测,为此本文深入杂散电流腐蚀的机理,运用电路理论推导杂散电流分布的理论公式,建立离散的供电理论模型。根据杂散电流的分布规律,分析了影响杂散电流的各个参数,设计了基于供电区间的有效的分布式轨道交通杂散电流监测模型。In order to protect the Urban Mass Transit, it was necessary to check and defense the stray current which rusted the reinforcing steel bar of the building near the railway. It was difficult to monitor the stray current directly on complicated environment, so the paper researched deeply on the principle of the stray current corrosion, the theory formula of stray current distribution was deduced by applying circuit net theory, and the discrete supply theory model was established. Accord with the distribution rule of the stray current, analyzing the different parameters of the stray current, a distributed and effective stray current monitor model of urban mass transit based on a power supply zone was designed.
