Abstract Research purposes: Considering the influence of high altitude on evacuation capacity and smoke diffusion in trains, the evacuation and rescue mode and new type of emergency rescue station in and out of high-altitude railway tunnel are discussed. At the same time, numerical simulation is used to analyze the law of smoke diffusion in high altitude and large longitudinal slope tunnel, so as to clarify the type and structural design parameters of the new emergency rescue station.
Research conclusions: (1) High-altitude railway tunnels can select two evacuation modes, i.e. evacuation outside the tunnel and evacuation inside the tunnel, based on factors such as climate environment outside the tunnel and safe evacuation time. (2) The external rescue of tunnel can adopt three rescue modes: railway rescue, road rescue and air rescue, the high altitude railway tunnels should adopt the mode of railway rescue. (3) It is recommended to adopt the new emergency rescue station rescue mode consisting of train fire parking area + isolation transition area + rescue train parking area in the high-altitude railway tunnel. (4) Both elevation and slope increase aggravate the spread of smoke in tunnel, and the influence of slope change on the spread rate of fire is more significant than that of altitude change. (5) The research results can guide the design of disaster prevention, evacuation and rescue engineering of high-altitude railway tunnel.

Key words： high altitude large longitudinal slope railway tunnel disaster prevention and evacuation emergency rescue station
