摘要
以某城市地下交通联系隧道(UTLT)为例,结合我国隧道通风设计规范的规定和该种隧道形式多进口多出口的具体特点,对UTLT这种隧道形式采取分段考虑的方法,并选取不同的行车速度,不同的车型比例和不同的预测交通量3个变量,研究3个变量对隧道需风量计算的影响。进而对该UTLT在射流风机纵向通风的方式下的压力模式进行计算,并对射流风机进行选型。
On the basis of a urban traffic urban link tunnel, it concerned about the specific characteristics of UTLT and tunnel ventilation design norms in China, using piecewise considering methods in this project. Three variables were selected and researched about their influence on the required quantity of air. Additionally, the pressure mode of the UTLT was calculated, selecting jet fan.
