Abstract
By taking the super-long railway tunnel as the object of research, based on setting problems of emergency stations adopted by super-long railway tunnels, from the viewpoint of people's safe evacuation, several aspects were studied, such as the mode of evacuation and rescue by adopting emergency station, the number and interval of the cross passage, and the people's safe evacuation time under different fire scenes at the emergency station. The basis for optimal design and construction of the emergency station in the super-long railway tunnel was provided, and it has vital practical significance to the perfection of fire emergency rescue and safe evacuation plan in super-long railway tunnels.
Highlights
With the development of railway construction projects, the number of the tunnels that have a length of more than 3km is nearly 200 in China [1, 2]
When the fired train stops at the emergency station, passengers should evacuate under the train crew's guidance immediately, all the people evacuate through the cross passage between two tubes to the refuge room, after the rescue train arrived, they can evacuate from the refuge room to the safe tunnel and take the rescue train to leave the tunnel

Summary
With the development of railway construction projects, the number of the tunnels that have a length of more than 3km is nearly 200 in China [1, 2]. The length of a railway tunnel of Qinghai-Tibet line which is under construction is more than 30km and its altitude is over 3300m, which belongs to the high-altitude super-long railway tunnel. This series long-large railway tunnel brought a lot of security issues. 196 The Open Civil Engineering Journal, 2017, Volume 11 large number of experiments and numerical simulations have been carried out to study the safe evacuation of tunnel personnel [13] They studied the evacuation channel spacing for personnel safety in railway tunnels and in highway tunnels. Based on a super-long railway tunnel, calculation model of personnel evacuation was established to research on the mode of evacuation and rescue by adopting emergency station in the super-long railway tunnel in this paper
