摘　　要：为研究近5km单向2%长大极限纵坡公路隧道的通风方案,采用定性分析与定量对比相结合的方法,对8个斜井和4个竖井通风方案进行比选,结果表明,综合风速均匀性、造价规模、环境影响及施工条件等因素,推荐鸿图特长隧道选用竖井通风,为粤东山区公路隧道通风设计提供了借鉴和参考。In order to study the ventilation scheme of nearly 5 km one-way 2% long limit longitudinal slope highway tunnel,the ventilation schemes of 8 inclined shafts and 4 vertical shafts are compared by using the method of qualitative analysis and quantitative comparison.The results show that considering the factors such as wind speed uniformity,cost scale,environmental impact,and construction conditions,the vertical shaft ventilation is recommended for Hong-tu Tunnel,which may provide a reference for the design and construction of similar project in Mountains of east Guangdong Province in the future.
