通过对茨哈峡隧道通风排烟原设计与现实施工进行研究，得出高原隧道通风设计时必须考虑一定的降效系数。同时由于该隧道单向贯通约3?5km，属于超长隧道，施工中通过对采用施工通风竖井排烟方案与大功率风机抽压混合排烟方案进行经济及工期对比，最终确定采用满足要求的大功率风机压抽混合式通风排烟方案。通过施工中的观测，得出大功率风机应用于超长隧道通风排烟切实可行。

The design and construction of the ventilation and smoke discharge of Cihaxia Tunnel is researched, and the conclusion is obtained that the reduction coefficient must be considered in the ventilation design at the plateau area. At the same time, because of the length of the tunnel is about 3?5km, belonging to the super-long tunnel , through comparing the construction ventilation and smoke discharge shaft scheme with high power pressure-pumping smoke discharge mixed programme in economic and time, the high power pressure-pumping hybrid ventilation and smoke discharge scheme is ultimately determined to be used. Through the observation in the construction, the application of high power fan using in the long tunnel to ventilation is practical.
