高原铁路某隧道斜井工区在通风方式选择上一直存在隔板式通风和风管式通风的争论。为给该斜井工区施工通风方式的选择提供参考，首先，采用通风网络计算的方法，对2种方式的通风系统进行分析计算。然后，根据计算结果和耗能的对比分析，得出如下结论： 1）隔板式通风和风管式通风均能使作业面的风速满足设计要求。2）当斜井中2根风管直径为2.2 m时，在风机配置相同的情况下，无论是第2阶段还是第3阶段，隔板式通风在耗能方面明显优于风管式通风。3）当斜井中2根风管的直径略大于2.5 m时，风管式通风的耗能与隔板式通风的耗能相当； 继续增大斜井风管的直径，其耗能将小于隔板式通风。最后，对类似单斜井双正洞模式的施工通风方式选择提出建议。

There has always been a controversy between partition and duct ventilation modes in the inclined shaft construction area of a tunnel of a plateau railway. Ventilation network calculation is conducted on these two modes. The calculation results and energy consumption are compared to provide a reference for selecting construction ventilation modes in the inclined shaft construction area. Some conclusions are drawn as follows: (1) The wind speed of the working surface under the two ventilation modes can meet the design requirements. (2) When the diameter of the air duct in the inclined shaft is 2.2 m, the partition ventilation has a better effect than the air duct ventilation in terms of energy consumption in both the second and third stages under the same fan configuration. (3) When the diameter of the air duct in the inclined shaft is slightly greater than 2.5 m, the energy consumption of air duct ventilation is equivalent to that of partition ventilation. The energy consumption of air duct ventilation will be less than that of partition ventilation if the air duct′s diameter is continuously increased. Finally, suggestions are given on selecting the construction ventilation mode for singleinclinedshaft and doublemaintunnel projects.
