摘　　要：从2011年至今,北京地铁5号线、八通线、13号线共发生轨道电路故障事件520起,其中道岔区段故障为128起,占轨道电路故障总数的24.62%,如此之高的故障率直接影响地铁运营安全。考虑采用计轴叠加轨道电路的工作方式,来解决轨道电路受道床电气特性及现场环境影响所引起的"红光带"问题。该方案实施后,有效解决轨道电路现有的安全隐患问题,提高设备可靠性、可用性、可维护性,在一定程度上保证地铁的正常运营秩序。Since 2011, a total of 520 track circuit fault events happened in Beijing subway line 5, Batong line and line 13, including 128 cases of the switch section faults, accounting for 24.62% of the total number of the track circuit faults. Such high failure rate directly affects the safety of the metro operation. The paper introduces the scheme of adopting the working style of axle counters overlapping the track circuit to solve the problem of track circuit ＂red zone＂ caused by electric ballast features and on-site environment. The scheme can effectively solve the existing safety problems of track circuit, improve equipment reliability, availability and maintainability, and can guarantee the normal operation of the metro to a certain degree.
