乐西高速大凉山 1号隧道设置了一条贯通平导和一座斜井,为探究平导用于运营通风的可行性和经济性,文章首先分析了平导的功能,可知平导用于运营通风不会与原有功能冲突;然后通过调整斜井和平导通风功能的分配,提出多种利用平导进行通风的方案;最后进行了通风计算,从多方面比较各方案的优缺点,得出平导用于通风可以在一定程度上减少综合费用,但工程难度及救援疏散组织难度都较高的结论.
Research on Ventilation Scheme of Daliangshan No.1 Extra-long Highway Tunnel
A through parallel pilot tunnel and an inclined shaft are set up in Daliangshan No.1 tunnel on Lexi Expressway.In order to explore the feasibility and economy of parallel pilot tunnel used for operation ventilation,this paper first analyzes the function of parallel pilot tunnel,and it is known that the parallel pilot tunnel used for operation ventilation will not conflict with the original function.Then,by adjusting the distribution of the ventilation function of the inclined shaft and the parallel pilot tunnel,a variety of ventilation schemes using the parallel pilot tunnel are proposed.Finally,the ventilation calculation is carried out,and the advantages and disadvantages of each scheme are compared from many aspects.It is concluded that the parallel pilot tunnel used for ventilation can reduce the comprehensive cost to a certain extent,but the engineering difficulty and the difficulty of rescue and evacuation organization are high.
