自然通风下高海拔公路单向隧道污染物扩散影响因素

摘要

Through the physical and mathematical model, from the tunnel length, traffic volume, inlet velocity, vehicle exhaust emissions and other aspects, this paper analyzed the main influence factors of high altitude highway one-way tunnel pollutant dispersion under natural ventilation condition, finally draw some meaningful conclusions.%通过物理与数学模型，从隧道长度、交通量、进口风速、汽车尾气排放量等方面，分析了自然通风下，高海拔公路单向隧道污染物扩散的主要影响因素，最终得出了一些有意义的结论。
