摘　　要：25 Hz相敏轨道电路与ZPW-2000A轨道电路特性不同,但在自动闭塞及站内电码化改造过程中两种制式轨道电路常结合应用。不同的特性会导致结合处的逻辑检查失效。针对场联进路无法正常解锁、三接近闭塞分区遗留失去分路故障进行分析,介绍故障发生的场景及原因,并讨论计算机联锁、列控中心、区间综合监控系统以及继电逻辑检查电路对于此类故障的解决方案,为后续工程设计及故障处理提供参考。The 25 Hz phase sensitive track circuit has diff erent characteristics from ZPW-2000A track circuit.However,during the retrofitting of automatic block and station coding systems,these two track circuits are often used together.The diff erent characteristics of these two track circuits may lead to the failure of logic check at their junction.This paper analyzes the failure of normal release of the yard connection route and the loss of shunting kept in the third approach block section,and introduces the scenario and causes of these faults.It also discusses the solutions of the interlocking system,train control center system,integrated section monitoring system and relay logic check circuit for these failures,which provides reference for engineering design and fault handling in the future.
