摘要
结合广州丁字形隧道通风设计项目,介绍了城市公路隧道通风设计的一般计算、设计方法,鉴于此隧道的特殊性——丁字形,指出在计算过程中需详细考虑通风方式,比较两个通道的阻力以确定风机的总升压力。
Combining with the ventilating design item of T-shaped tunnel in Guangzhou,the general calculation and design methods of ventilating design in urban highway tunnel were introduced.Considering the specialty of this tunnel that T-shape,it pointed out that the ventilating types were needed to consider in calculation process,comparing the resistance pressures of two channels to ensure the total rise pressure of fan.
