摘　　要：研究目的:为分析多因素下活塞风对地铁车站影响特性,本文以出入口及站台门的进风量为主要分析对象,通过数值模拟和理论分析来研究站台门风口开启面积、活塞风阀开启面积、行车周期及有无迂回风道下活塞风对车站的影响。研究结论:(1)出入口进风量随行车周期的增大先增大后变小,而站台门进风量随着行车周期的增大而减少;(2)单纯地改变站台门风口开启面积对增强活塞风对车站的影响是有限的;(3)屏蔽门单活塞系统模式,建议增设迂回风道,可根据需求调节迂回风道的开关,进而控制和利用活塞风效应对地铁车站的通风量;(4)活塞风阀开启面积越小,出入口进风量越大,活塞风对车站的影响也越大,配合控制站台门风口开启面积与活塞风阀开启面积,能很好地控制活塞风对车站的影响;(5)从方差分析结果可以得出,活塞风阀开启面积对出入口进风量影响最为显著,而站台门风口开启面积对站台门进风量影响显著程度最高;(6)本研究结果能很好地指导环控系统方案设计,为活塞风的控制和利用提供理论基础。Research purposes: In order to analyze the influence of piston wind on the subway station under multi-factor,this paper takes the inlet air volume of the entrance and platform door as the main analysis object,and studies the influence of piston wind on the station by numerical simulation and theoretical analysis,including the opening area of platform door,the opening area of the piston wind valve,the driving cycle and the bypass.Research conclusions:( 1) The inlet air volume first increases and then decreases with the increase of the driving cycle,while the inlet air volume of the platform door decreases with the increase of the driving cycle.( 2) The effect of simply changing the opening area of platform door on enhancing piston wind on the station is limited.( 3) In the mode of platform screen door single piston system,it is suggested to add a bypass. The switch of the bypass can be adjusted according to the needs,so as to control and make use of the piston wind effect on the ventilation of subway station.( 4) The smaller the opening area of the piston wind valve,the greater the air volume at the entrance,and the greater the influence of the piston wind on the station. With the control of the opening area of the platform door and the opening area of the piston wind valve,the influence of the piston wind on the station can be well controlled.( 5) From the results of variance analysis,it can be concluded that the area of piston air valve has the most significant influence on the entrance air volume,while the opening area of platform door has the most significant influence on the inlet air volume.( 6) The research result can well guide the design of environmental control system and provide a theoretical basis for the control and utilization of piston wind.
