关角隧道是世界高海拔第一长隧，共设10座辅助斜井，无轨运输系统组织施工，斜井工区施工通风难度大。介绍施工通风斜井分隔方案的设备布置、能耗分析、中隔板结构形式、防漏风措施等技术，通过斜井分隔方案在关角隧道10号斜井的现场应用和通风效果测试，表明斜井分隔方案可以在无轨运输斜井的施工通风中推广应用。

Guanjiao tunnel is the longest high altitude tunnel in the world. 10 assistant inclined shafts are set for the tunnel and trackless transportation system is used in each inclined shaft. The ventilation of the inclined shaft work lots during tunnel construction is difficult. This paper aims to introduce the equipment layout, energy consumption analysis, false ceiling structure and air leakage prevention measures of inclined shaft partition method used for ventilation during the tunnel construction. The ventilation effect of the inclined shaft partition method used in the 10th inclined shaft work lot of Guanjiao tunnel demonstrates that the inclined shaft partition method can be promoted in the ventilation of inclined shafts with trackless transportation systems.
