摘要
为了分析单向坡特长公路隧道通风系统的特殊性,并满足其正常行车环境卫生标准和火灾排烟问题,采用需风量分析及多方案技术经济综合比较的方法,用单斜井送排式纵向通风模式解决了上坡隧道与下坡隧道需风量不平衡及火灾排烟问题。
In order to analyze the characteristics of tunnel ventilation system with unidirectional longi-tudinal slope and to meet the health standards of its normal driving environment issues and smoke ex-hausting in case of fire,the analysis of air demands and economic comprehensive comparative of sever-al schemes is performed.Finally,a blow and exhaust ventilation model with one inclined shaft is used to solve the problem of air demands unbalance between the uphill and downhill tunnel and fire smoke control.
