摘要
通过数值分析,对地铁隧道通风系统进行了研究,从改变进气温度的角度研究了风井合并问题,提出室外合并风井的方案.该方案在不影响地铁内部功能的前提下,减少了地面风井的数量,从而节省征地、减少地铁建设投资.
Through numerical value analyses,this paper studied the ventilation system of subway tunnel,and investigated the problem of combination of wind well from the point of view of changing the inlet air temperature and presented the scheme of combining wind well outdoors. Under the precondition of no influence upon the inner function of subway,this scheme reduced the number of surface wind well so as to economize the requisition by purchase of land and lessen the investment of subway.
