摘要/Abstract

摘要： 为探究超长公路隧道火灾模式下的通风系统控制，针对天山胜利隧道提出了基于烟气及疏散双因双控下的防灾区间划分方法，采用通风网络的分析方法，考虑了高海拔环境及隧道多折线坡度，对各防灾区间内不同位置处发生火灾时的多交叉口风流进行了全隧道通风系统控制计算，获得了左、右线主隧道、服务隧道及横通道的防灾风机布置数量及位置。结果表明，天山胜利隧道考虑控烟、疏散、机电控制因素将左、右线分别划分为31和30个防灾分区，并确定了风机布置的具体区段及数量，其中左、右线主隧道分别设置了112、114台SDS112T-4P-37风机，服务隧道分别设置了168台SDS63T-2P-15风机。

Abstract: Abstract: In order to explore the control of ventilation system under the fire mode of super-long highway tunnel, a method of dividing disaster prevention intervals based on the dual control of smoke and evacuation was proposed for TianshanShengli Tunnel. By using the analysis method of ventilation network, considering the high altitude environment and the slope of tunnel polyline, the ventilation system control calculation of multi-intersection airflow in different positions of each disaster prevention interval was carried out, and finally the number and position of disaster prevention fans in the service tunnel, cross passage and main tunnel on the left and right lines were obtained.The results show that the TianshanShengli Tunnel has divided the left and right lines into 31 and 30 disaster prevention zones considering smoke control, evacuation, and electrical and mechanical control factors, and determined the specific sections and number of wind turbines. The left and right main tunnels have 112 and 114 SDS112T-4P-37 wind turbines respectively, and 168 SDS63T-2P-15 wind turbines were installed in the service tunnel.
