太行山特长隧道防灾通风方案探讨

Discussion on Disaster Prevention Ventilation Scheme of Taihangshan Long Tunnel

根据太行山隧道防灾救援具有多个进、出口通风的特点,运用网络通风理论,建立隧道复杂通风系统的计算模型。针对1号救援站防灾救援利用5号斜井送风、专用竖井排烟的纵向式通风方案进行计算对比分析,结果表明,该通风方案可以优化为取消专用竖井,利用5号斜井或隧道排烟,这样既减少了工程投资,又便于运营管理。

Considering the features of disaster prevenlion ventilation scheme for Taihangshan tunnel with many entries and outlets, a complex tunnel ventilation calculation model was established by using network ventilation theory. To implement longitudinal ventilation scheme with No.l rescue station as the main rescue station and by utilizing No.5 inclined shaft to supply fresh air and a special shaft to exhaust smoke, comparative calculations were carried out. Results showed that this scheme can be optimized to cancell the special shaft using No.5 inclined shaft or tunnel itself to exhaust smoke, thereupon to reduce project investment and to be more convenient for operation management.
