高原缺氧地区长斜井隧道通风探讨

Tunnel ventilation of inclined shaft in hypoxic areas of the plateau

针对高寒缺氧斜井施工过程中的通风问题,以青藏铁路西宁—格尔木增建第二线的关角隧道为例,结合工程实际情况进行了方案比选,并介绍了实施过程中的参数计算方法,通风方式及管理措施,从而达到了合理的通风效果,积累了一定经验。

Aiming at the ventilation problems in construction of inclined shaft in hypoxic areas of the plateau,and taking Guanjiao tunnel in the second lane of Qingzang railway from Xining to Ge ermu stage as example,the paper compares the scheme combining practical situation,it also introduces calculation method of parameter in construction,ventilation style and management measure,so as to reach good ventilation effects and accumulate experiences for such kind of construction.
