基于CTCS制式的市域（郊）铁路车站股道有效长优化方案研究

Optimization Scheme for Effective Track Length at Suburban Railway Stations Based on CTCS Standard

摘要:
目的通过优化设计，缩短市域（郊）铁路车站股道有效长，以实现压缩站场规模、减少占用土地、降低建设成本的目的。
方法分析了市域（郊）铁路股道有效长的组成部分，基于CTCS（中国列车控制系统）的保护距离特点，介绍了优化侧线股道轨道电路设置方案。
结果及结论 通过优化设计方案，实现了缩短股道有效长的目标。贯通式股道有效长可缩短至321 m，尽头式股道有效长可缩短至291 m。

Abstract:
Objective Through optimized design, the effective track length at suburban railway stations is shortened, achieving the goal of reducing the station yard scale, downsizing land occupation, and lowering construction costs.
Method The components of the effective track length for suburban railways are analyzed. Based on the protection distance characteristics of CTCS (Chinese Train Control System), an optimized layout scheme for siding track circuit is introduced.
Result & Conclusion Through the optimized design scheme, the goal of shortening the effective track length has been achieved. The effective length of through tracks can be shortened to 321 m, and the effective length of dead-end tracks to 291 m.
