Development of New Technologies for Ventilation,Oxygen Supply,  Disaster Prevention and Energy Saving for High altitude Tunnels

The recent studies of high altitude tunnels are summarized in terms of construction, ventilation, disaster prevention and rescue, energy saving ventilation so as to guarantee the rapid development of high altitude tunnel in China. The ventilation control standard, fan characteristics, oxygen supply during construction in high altitude, low pressure, low oxygen and low temperature environment are obtained. The characteristics of fire and smoke flow in high altitude tunnels are identified. The method for determining personnel escape ability and evacuation structure parameters in high altitude tunnels is demonstrated. Finally, the development and application of new energy saving technologies for ventilation and illumination in high altitude tunnels are introduced.
