摘　　要：研究目的:基于正交试验原理,对典型地铁车站冬季热环境的影响因素进行分析,得出各影响因素主次顺序和提高车站热环境最优方案配置,从而指导北方地区冬季地铁车站站台门的选择及运营策略的制定。研究结论:(1)影响站厅温度的因素主次顺序为:土壤温度Tsoil>室外温度Tw>活塞风井开启数量δ>客流量fv>站台门开口面积s>行车周期tf;(2)影响站台温度的因素主次顺序为:土壤温度Tsoil>室外温度Tw>客流量fv>行车周期tf>站台门开口面积s>活塞风井开启数量δ;(3)采用单活塞系统时,车站平均温度达到最大值;采用闭式模式运行时,车站平均温度最低;(4)相比于安全门,北方地区冬季地铁站采用屏蔽门系统更能有效提高车站温度;(5)本研究结果可为北方地区地铁车站热环境控制提供理论基础。Research purposes:Based on the principle of orthogonal test,the factors affecting the thermal environment of typical subway stations in winter are analyzed,and the order of the influencing factors and the optimal operation scheme are obtained,to guide the selection of platform edge doors and the formulation of operation strategies for subway stations in winter in northern China.Research conclusions:(1)The primary and secondary order of the factors affecting station hall temperature is:soil temperature(Tsoil)>outdoor temperature(Tw)>the number of piston vent shaft(δ)>passenger flow rate(fv)>platform door opening area(s)>train cycle(tf).(2)The primary and secondary order of the factors affecting station platform temperature is:soil temperature(Tsoil)>outdoor temperature(Tw)>passenger flow rate(fv)>train cycle(tf)>platform door opening area(s)>the number of piston vent shaft(δ).(3)When the single piston system is adopted,the average station temperature is the maximum and when the closed mode operation is adopted,the average station temperature is the lowest.(4)Compared with the platform bailout door(PBD),the platform screen door(PSD)is more effective to improve the station temperature in winter in northern China.(5)The research results can provide a theoretical basis for the thermal environment control of subway stations in northern China.
