【摘要】 为了最大程度地发挥射流风机在双洞单向公路隧道纵向通风中的潜力,针对相邻两条上、下行隧道内通风负荷相差较大的特点,根据隧道通风基本理论,对一种新型的隧道通风换气方法——空气交换进行了较详细的研究,给出了该方法在公路隧道纵向通风中的应用范围和具体的设计算法,并利用其对某隧道进行了简要的通风设计计算。结果表明,该隧道采用空气交换方法构建的通风换气系统后,节约了隧道通风系统的初投资和运营费用。更多还原

【Abstract】 In order to give full play to the potential longitudinal ventilation capacity of jet fans in a double-tube one-way highway tunnel,considering the different ventilation loads between two adjacent up-line and down-line tunnels and the basic theories of tunnel ventilation,the paper carried out a detailed study on a new-type tunnel ventilation by air exchange,and also provided the design and computation method,utilized to perform the ventilation design of a tunnel.Results indicate that if the tunnel ventilation system is constructed by the air exchange principle,the initial cost and operating cost for ventilation can be reduced.更多还原
