Abstract:Research purposes: Prevention and Rescue of disasters happening in extra-long tunnels or tunnel groups is related to the operation safety of the train. According to Code for Design on Evacuation Engineering for Disaster Prevention and Rescue of Railway Tunnels, extra-long tunnels or tunnel groups longer than 20 km should set up an emergency rescue station. But how to combine the design of the concrete project with the emergency station is worthy of research. The paper is valuable for similar engineering design and revision of the norms.
Research conclusions: The paper introduces the main principles and contents of the design of the emergency rescue station of Qingyunshan tunnel, It is concluded that:(1) It should consider circumstances of each tunnel, including its structural type, construction methods and auxiliary tunnel arrangements, etc to design individual emergency station; (2) The emergency rescue station design should be rational allocation of personnel safety evacuation and temporary shelter construction facilities, reasonable tunnel ventilation and smoke exhaust scheme, scientific layout of disaster prevention and rescue system,related to disaster prevention and rescue measures are reasonable and effective; (3) It should regard prevention and rescue of disasters in railway tunnels as a systematic engineering, which implies systematic maintenance, management and commanding is the key of the system; (4) The research results has a certain reference value for similar engineering design and revision of the “norm”.
