摘要： 对《公路隧道通风照明设计规范》(JTJ 026.1-1999)中的车密度系数进行讨论,推导了不同情况下,机动车在隧道内行驶路程的表达式;证明了一定交通量下的机动车在隧道内行驶路程与车密度无关,即交通量一定时公路隧道通风需风量与车密度与无关。又讨论了交通量与车速的关系,指出车密度系数实际上是对不同速度交通量的修正,所以此系数的意义和取值需要重新考虑。

Abstract: The vehicle flow density factor in Specifications for Design of Ventilation and Lighting of Highway Tunnel was discussed, and the formula expressions of vehicle traveling distance in tunnel were deduced to conclude that the tunnel ventilation flow rate is not related to the vehicle flow density under certain traffic flow rate. Afterwards, the relationship between vehicle speed and traffic flow rate was discussed, which led to the point that the vehicle flow density factor is the amendment of traffic flow rate actually and its value should be reconsidered on the base of certain traffic flow theory.

Key words: tunnel engineering, ventilation flow rate, traffic flow rate, vehicle speed, vehicle flow density factor
