摘　　要：随着国内隧道建设规模的不断扩大,高山峡谷区修建了大量长大公路隧道。合理经济的通风方案要能在运营期内稀释有害气体和降低粉尘,保证行车舒适性;在火灾工况下实现排烟救援。因此,隧道通风方案设计既要考虑通风结构的工程规模,降低建设期造价,又要对比方案选择合理的通风方式,降低运营期费用和能耗。论文以大岩隧道通风方案优化设计为例,为两车道公路隧道通风设计提供参考,提出地质条件优选通风方案的设计思路。With the continuous improvement of tunnel construction scale in China,a large number oflong highway tunnels have been built in the high mountains and valleys.Reasonable and economic ventilation scheme should not only dilute harmful gases and reduce dust to ensure driving comfort during operation period,but also smoke exhaust and rescue under fire conditions.It should not only consider the engineering scale of ventilation structure to reduce the construction cost,but also choose reasonable ventilation mode to reduce the cost and energy consumption during operation period.Taking the ventilation scheme optimization design of Dayan Tunnel as an example,this paper provides reference for ventilation design of two-lane highway tunnel,and puts forward the design idea of optimizing ventilation scheme under geological conditions.
