摘要: 规划中的南水北调西线工程地处海拔高程3 000 m以上的青藏高原,高原高寒缺氧为主要气候特点。输水线路隧洞长244 km,最长洞段73 km,TBM单工作面掘进长度达25 km,考虑布置通风竖井通风,独头通风距离将达到14 km,在国内外隧道工程中都是罕见的。对通风设备、通风系统进行研究,提出14 km独头通风解决方案,为西线工程提供参考。

Abstract: The SouthtoNorth Water Transfer Project is located on 3 000 mhigh Tibetan Plateau, where it is cold and oxygen is insufficient. The total length of the water transfer tunnels is 244 km. The longest tunnel is 73 km long, for which the TBM drives 25 km distance in one single direction. One ventilation shaft is to be installed, therefore the singledirection ventilation distance reaches 14 km. In the paper, study is made on the equipment and system for the 14 kmlong singledirection ventilation and proposal is made on the 14kmlong singledirection ventilation program. 

Key words: SouthtoNorth Water Transfer Project, tunnel, ventilation during construction
