摘要 研究目的：市域线以地面、高架的明线敷设方式为主,其明线段线间距将直接影响线路设计、桥面布置、工程投资等。国内市域线明线段线间距选取差异较大,既有研究对线间设置建（构）筑物的工况指导性不强。本文通过设定选取原则、分析影响因素、确定典型工况、经济技术比选等方式,对市域线明线段区间合理线间距进行研究,提供一套适用性较强的选取方法。
研究结论：（1）提出市域线明线段合理线间距的选取方法：首先根据车型确定直线段最小线间距,之后根据线间建（构）筑物、梁型确定直线段合理线间距,最后根据曲线加宽、施工方法修正区间合理线间距;（2）结合限界要求宜将市域B型车最小线间距调整为3.4~3.6 m;（3）从控制投资角度,线间不宜设置建（构）筑物;从整体功能性角度,线间宜设置疏散通道,接触网支柱设置于两侧;（4）确定了各种车型在曲线地段需要加宽线间距的数值及曲线半径范围;（5）本研究成果可为市域线线间距的选取提供借鉴和参考。

Abstract：Research purposes: The regional railway is mainly laid in the form of ground and elevated, and the line spacing will directly affect the line design, bridge deck layout, engineering investment, etc. There is a significant difference in the selection of line spacing in domestic regional railways, and the existing research lacks strong guidance on the working conditions of building (structure) installation between lines. This article conducts research on reasonable line spacing by setting selection principles, analyzing influencing factors, determining typical operating conditions, conducting economic and technological comparisons, and providing a set of highly applicable selection methods.
Research conclusions: (1) This paper proposes a method for determining the reasonable line spacing of regional railways: Firstly, determining the minimum line spacing of straight sections based on the vehicle model. Secondly, determining the reasonable spacing between straight lines based on the buildings, equipment, and beam types. Thirdly, adjusting the reasonable line spacing based on curve widening and construction methods. (2) Suggest adjusting the minimum line spacing of B-type vehicles to 3.4~3.6 m based on the limit requirements. (3) From the perspective of controlling investment, it is not advisable to set up buildings or structures between lines; From an overall functional perspective, evacuation routes should be set up between lines, and overhead contact system pillars should be set on both sides. (4) The values and curve radius range for widening the line spacing in curved sections have been determined for various vehicle models. (5) The research results can provide useful references for the selection of regional railway line spacing.

Key words： regional railway reasonable line spacing curve widening evacuation platform
