摘要
建立了西安地铁两条运营线路的SES模型,对联络线连通前、后隧道风量、活塞风井风量以及隧道空气温度的变化进行了计算分析,结果表明:隧道风量最多变化了57.75m^3/s;风量变化最大的活塞风井排风量增加了33.59m^3/s,进风量减少了22.61m^3/s;隧道空气温度最多上升了0.67℃。以上变化最大值均出现在联络线前后两个车站范围以内。
In this paper,the SES model of two operation lines of Xi'an Metro is established,and the changes of tunnel air volume,piston air shaft air volume and tunnel air temperature before and after connecting the connecting lines are calculated and analyzed.The results show that:the maximum change of tunnel air volume is 57.75m3/s;the piston air shaft with the largest air volume change has an increase of 33.59m^3/s in exhaust air volume and a decrease of 22.61m^3/s in intake air volume;the air temperature in the tunnel increased by 0.67℃at most.The maximum changes above are within the scope of two stations before and after the connecting line.
