东秦岭隧道进口段施工通风设计

Ventilation design for the entrance of East Qinling tunnel

通过对竖井、斜井、巷道式施工通风方案的分析比较,证明在东秦岭隧道进口段采用斜井式通风方案是切实可行的。文章叙述了斜井通风系统的设计计算以及隧道正洞与平导的通风布局。

After analyzing and comparing various construction ventilation programs by use of a shaft, an inclined shaft or a gallery at the entrance section of East Qinling tunnel, this paper presents the design and calculation of ventilation alternative by use of a inclined shaft.
