本文根据对列车在隧道中的活塞作用的分析和在我国隧道通风试验中已得到证实的活塞压差公式提出一种计算单孔、无竖井隧道空气阻力定常值的方法。
Based on the analysis of the piston action of the train in the tunnel and the piston pressure difference formula which has been proved in the tunnel ventilation test in our country, this paper presents a method to calculate the constant value of the air resistance of a single-hole tunnel without a shaft.
