摘　　要：中国城市轨道交通广泛采用1500V直流牵引,因此,钢轨既是轨道电路信号的传输媒介,同时也是牵引回流的通道。在上海地铁2号线和天津滨海轻轨等项目的正线道岔区段、车辆段和停车场应用单轨条50Hz相敏轨道电路。根据上述项目的工程调试经验,对单轨条50Hz相敏轨道电路的原理和实践应用中的几个问题进行探讨。DC 1 500 V power is widely applied in urban mass transit in China, both track circuit current and traction return current are transmitted through rail. 50 Hz single-rail phase detecting track circuit has been applied in switch section of mainlines, depots and yards in Shanghai Metro Line 2 and Tianjin-Binhai light rail transit project. The principles and problems in practical application of 50 Hz single-rail phase detecting track circuit are discussed based on commissioning experiences of the projects abovementioned.
