摘要
青藏铁路风火山隧道海拔高4900m，缺氧、严寒的气候及多年冻土的地质环境，对施工人员健康及工程质量造成极大威胁。成功研制与使用的高原专用施工通风系统、供热系统及洞口制氧、供氧系统，有效地改善了洞内施工作业环境，为工程的成功建设提供了重要技术保障。
The altitude of Fenghuoshan tunnel on Qinghai to Tibet railway is 4900m.The climate of oxygen lack and severe cold and the geological environment of permafrost endanger workers＇ health and construction quality. Special ventilation system, heat supply system and oxygen supply system are developed and applied in construction practice to improve tunnel construction environment .
