高等级公路长隧道的通风设计以往都采用横向式或半横向式，纵向式射流通风只是近几年才用于公路隧道。本文详细地介绍了乌石山隧道纵向式射流通风设计，可供设计人员在进行其他公路隧道通风设计 时参考。

In the past times, the transverse ventilation design or semi-transversal ventilation design were usually adopted for the long tunnel on high-rank highways, while the longitudinal injection ventilation design was only adopted in recent few years. The paper introduces in detail the longitudinal injection ventilation design for the Wushishan Tunnel, which may be used as reference for the ventilation design of other highway tunnels.
