By taking the 32.645-kilometer-long Guanjiao tunnel of Qinghai-Tibet railway as the object of research, the technology of disaster prevention and rescue in the high-altitude super-long railway tunnel was studied. Combined methods of fire model test and numerical simulation, combustion characteristics in the high-altitude super-long railway tunnel were discussed, and the Available Safety Evacuation Time (ASET) was obtained. From the viewpoint of people’s safety evacuation, software called STEPS was used to establish the personnel evacuation model aimed to simulate the process of the personnel evacuation and analyze the evacuation time under different fire scenes at the emergency station. Setting schemes of the emergency station and the cross-passage of Guanjiao super-long railway tunnel were determined preliminarily, and it also provided a basis for optimizing the design of safety evacuation facilities of the super-long railway tunnel.

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.
