摘要
研究目的:采用实测与一维数值模拟相结合的方法,在不同站台门型式和运行阶段下,对兰州地区冬季地铁热环境进行分析研究,结合当地气候特点,旨在找到合适的站台门型式和运行策略。研究结论:(1)地铁运行初期,安全门开式运行其车站温度优于安全门闭式运行,屏蔽门闭式运行车站和隧道温度略优于开式运行,屏蔽门开式运行隧道和车站温度略优于安全门开式运行;(2)地铁运行初期,室外温度过低(低于-10℃)时,建议采取闭式运行方式,但此时出入口需采取有效措施,减少活塞效应引起从出入口的进风量;(3)地铁长期运行后,安全门系统开式运行,车站温度优于闭式运行,屏蔽门闭式运行时车站和隧道温度略优于开式运行,安全门开式运行车站温度优于屏蔽门开式运行;(4)本研究结果可为兰州及相似地区站台门型式的选择以及不同站台门型式下初期、远期的冬季运行策略的制定提供依据或支撑。
Research purposes： Combined on-site measurement and one-dimensional numerical simulation,subway thermal environment during winter in Lanzhou was analyzed under different types of platform gates and operation stages,to find the reasonable platform door pattern and operation strategy by combining local climate characteristics.Research conclusions：（ 1） In the initial stage of subway operation,the station temperature of open mode operation of platform bailout door（ PBD） is better than its close mode operation. The station and tunnel temperature of open mode operation of platform screen door（ PSD） is slightly better than that of PBD,and close mode operation of PSD is slightly better than its open mode operation.（ 2） In the initial stage of the subway operation,when outdoor temperature is lower than-10°C,close mode operation is recommended,but entrances and exits need to take effective measures to reduce airflow induced by piston effect.（ 3） In the long-term operation,the station temperature during open mode operation of PBD is better than its close mode operation,and the station temperature is also better than open mode operation of PSD.The station and tunnel temperature during close mode operation of PSD is better than its open mode operation.（ 3） This research result can provide basis for the selection of platform gate types and the formulation of initial and long-termoperating strategies in Lanzhou and other places with similar climate in winter.
