| Abstract: | In combination with terrain, climate and meteorological conditions of Zhangzhuo Expressway Fenshuiling Extra-long Tunnel, based on deducting the formula of tunnel ventilation rate per hour, this paper puts forward reasonable ventilation rate of needed air flow rate for diluting odor in Fenshuiling Tun- nel, and then puts forward the ventilation standard according to the corresponding regulation. In addition, the revision method for computing natural wind resistance is presented to make full use of the dynamic ac- tion of the winter and summer natural wind in Fenshuiling extra-long tunnel to realize economically via- ble fan configuration of ventilation system. It can provide reference for operation and ventilation system optimization design of the similar extra-long tunnels. |
