摘　　要：根据均匀传输线和四端网络理论,建立ZPW-2000无绝缘轨道电路分路电流的计算模型,利用MATLAB软件实现相邻区段干扰电流的数值算法,对轨道电路正常情况、调谐单元故障情况下邻区段干扰电流的分布进行仿真。Based on the theory of uniform transmission line and four-terminal network,this paper presented a simulation model of adjacent segment interference in the ZPW-2000 jointless track circuit.The numerical algorithm for current interference of adjacent segment was established with MATLAB.Simulation calculation was carried out based on the conditions such as track circuit in normal state,tuning unit open-circuit fault condition of adjacent segment interference current.
