摘　　要：为了降低特长铁路隧道通风系统运营费用,优化防灾通风方案,本文根据通风网络解算基本理论,分析了隧道防灾通风气流组织情况,计算了隧道火灾引起的附加阻力,采用矿井通风网络解算程序MVNS2.0对某隧道进、出口及斜井射流风机在不同组合模式下的防灾通风进行了风网解算。结果表明,利用风网解算软件对特长铁路隧道通风系统进行多方案分析,可以提高通风系统计算效率,合理确定风机组合方式,减少通风系统装机功率。For reducing the operation cost and optimizing the design of fire prevention ventilation, based on the fundamental method of ventilation network simulation, the air distribution of fire prevention ventilation is analyzed, additional resistance caused by tunnel fire is calculated and various ventilation networks of different combinations of one or several jet fans at tunnel entrance, exit and slope are calculated by mine ventilation network simulation （ MVNS2.0 ） in this paper. Results indicated that the efficiency of ventilation can be improved and the reasonable fans＇ combination can be set up and the installed power of ventilation can be reduced.
