特长隧道互补式通风方式研究

Study on complementary ventilation of super long tunnel

依托牛金山隧道,从设备规模、运营成本、土建费用、施工工期等方面对双洞互补与通风斜井相结合的通风方式进行研究。结果表明此种通风方式节省了机电及土建投资,经济效益可观,尤其适用于某些地形条件复杂苛刻、需增设通风井来满足通风要求的特长隧道。

Relying on the Niujinshan tunnel,this paper studies the ventilation mode of the combination of two-hole complementary ventilation and inclined ventilation shaft from the aspects of equipment scale,operation cost,civil construction cost,construction period,etc.,the results show that this ventilation method can save the cost of mechanical,electrical and civil construction,and the economic benefit is considerable.
