摘要：研究目的：关于普速铁路无配线股道的方向电路设计，目前尚无相关的标准规范对其作出明确规定。普 速铁路的无配线股道的方向电路通常存在两种设计方案，但是在使用过程中均暴露出一些问题。本文以春申 站为例对其适用情况进行分析，并研究其进一步优化设计的措施。 研究结论：( 1)普通无配线车站不作为方向电路控制点；（2)带无配线股道的车站，其无配线股道不宜作 为方向电路控制点，若本站有独立改方的运输需求，也可作为方向电路控制点，但应在邻站计算机联锁里增加 检查方向的条件;（3)类似春申站这种既有双侧无配线股道，又有单侧无配线股道的特殊车站，其无配线股道 可作为方向电路控制点并增加“接车前检查方向，接车后锁定方向”的优化处理措施；（4)该研究成果可为类 似车站的方向电路的设计提供借鉴。

Abstract：Research purposes: Usually there are two design schemes of the running direction circuit of normal speed railways switchless track. But in daily use，the two design schemes all expose some problems. Taking Chunshen Station as an example，this paper analyses the application of the two design schemes，and discuss the measures for further improvement. Research conclusions :(1) Common railway switchless station is not as the control point of the running direction circuit. (2) The switchless track of the common station should not be the control point of t!ie running direction circuit. / this station needs to change the running direction independently，it can also be the control point with checking the running direction in the computer interlocking of the adjacent station. (3 ) The switchless track of the special railway station such as Chunshen Station can be the control point of t!ie running direction circuit，but it should take optimized measures of 11 check the running direction before receiving the train， maintain the running direction after receiving the train. (4 ) The research results can provide references for the design of running direction circuit for the ot!ier similar stations.
