雁门关公路隧道通风方案

Ventilation scheme of Yan Menguan highway tunnel

从地理环境、气候条件、工程地质、交通流量、土建投资、运营费用以及防火救灾功能等方面,详细研究了雁门关公路隧道的七种通风方式,通过多方案的技术经济比较,给出了雁门关公路隧道的通风方案。通过数值模拟方法,给出了推荐方案的隧道风压、风速和污染物浓度变化曲线。

Considering the geographic environment,climatic condition,engineering geology,traffic volume,construction investment,operation cost,fireproofing and emergency rescue,seven ventilation plans for Yan Menguan tunnel were designed.By economic and technological comparison of these plans,the ventilation method was decided.By numerical simulation,the air pressure,velocity and the changing graphic of pollution concentration in the suggested method were discussed.
