地铁起止站的配线区间风井布置方案研究

摘要

With the rapid development of rail transit construction in recent years,the difficulty of subway ventilation and e-vacuation also attracts more and more attention.Combined with the design of Xi’an Metro Line 4 and the North Railway Station of Xi’an Airport Line,the setting of ventilation shaft at the ancillary routes behind the subway terminus station is analyzed and discussed,the necessity of setting interval ventilation shaft is determined,and some layout schemes of the shaft is taking into account.Through analysis and comparison of the boundary conditions along with the advantages and dis-advantages,the final design scheme is finalized.This paper can provide a reference for future design of terminus station which need setting ventilation shaft at the ancillary routes tunnel for similar projects.%随着近年地铁轨道交通建设的大跨步发展，地铁区间通风疏散问题也越来越受关注。结合西安地铁四号线及机场线北客站，对地铁起止站的站后配线区间风井的设置进行了分析讨论，明确了设置区间风井的必要性，并考虑了其布设的几种方案，分析比较了其控制边界条件及优缺点，提出了最终设计方案，可为今后类似的地铁起止站的站后配线区间风井设置工程设计提供相关参考。
