高寒、高海拔隧道施工技术研究

Research on Construction Technology of Alpine and High Altitude Tunnels

针对高海拔、缺氧、低温的特殊环境,介绍米拉山隧道机械设备的选型、洞内施工环境、制氧与供氧系统等,通过研究、实践、总结、改进、提高,获得了在高海拔高寒地区修建隧道的基本经验和关键施工技术,为我国西部大开发,修建高海拔、高寒地区公路、铁路隧道提供施工参考和经验总结。

In view of the special environment of high altitude,hypoxia and low temperature,this paper introduces the selection of mechanical equipment,construction environment,oxygen production and oxygen supply system of Mira Mountain Tunnel,which is improved through research,practice,summary,improvement.The basic experience and key construction technology of tunnel construction in high altitude and cold area are obtained,which provides reference and experience for the development of western China and the construction of highway and railway tunnel in high altitude and cold area.
