| 摘 要： | 高海拔低气压地区因其海拔高、气压低、空气密度小，通风机的性能在高原地区与在平原地区相比发生了改变。针对这一特点，分析高原地区影响通风机压力及风量的因素，介绍解决通风机在高原地区性能改变的方法、隧道施工宜采用的通风方式以及高原地区施工通风还应采取的其他一些辅助措施。

| Abstract: | Because of the high altitude,low air pressure and low air density in plateau area,the performance of the ventilators in plateau area is different from that in plain area.The factors that influence the air pressure and air volume of ventilators in plateau area are analyzed.Solutions for the performance changing of ventilators in plateau area,appropriate ventilation methods and assistant measures for tunnel construction ventilation in plateau area also presented. |

| Keywords: | high altitude low atmospheric pressure tunnel ventilation in construction air density air speed |
