浅谈高海拔条件下长距离独头通风技术

A Brief Discussion on Long Distance Single-head Ventilation Technology at High Altitude

我国海拔4000m以上、独头通风长度4000m的隧道很少,公路隧道至今也没有针对高海拔严寒地区复杂地质条件下修建隧道的相关设计与施工规范。施工阶段的通风关系到高海拔隧道施工安全。通过科学优化通风系统,实现了良好的通风效果,保障了施工安全和施工人员的身心健康,进而达到隧道高效掘进的目的,为以后类似项目的施工提供经验参照。

4000 m above sea level in China,only very little head ventilation tunnel length 4000 m,highway tunnel was not aimed at high elevation cold region to build a tunnel under complicated geological conditions of the relevant design and construction.Ventilation during construction is related to the safety of high altitude tunnel construction.Through scientific optimization of ventilation system,to achieve the good ventilation effect,ensure the construction safety and construction personnel＇s physical and mental health,thus to achieve the purpose of excavating high tunnel,to provide experience for construction of similar projects in the future.
