Research on the structure type of emergency rescue station in super-long railway tunnel

Abstract

In order to ensure the safety of rescue and evacuation of super-long railway tunnel (longer than 20km), an emergency rescue station is generally set up. Through the research on the structure types of the railway tunnel and the railway tunnel group emergency rescue stations at home and abroad, the paper finds out the types of the emergency rescue stations and the advantages and disadvantages of different structural types. Conclusion are as follows,| Super-long railway tunnels in European countries, Japan and China generally adopt the form of double holes. Super-long railway tunnels generally use a single hole in China.| There are six types of structure of railway tunnel emergency rescue station: general encryption transverse channel type, horizontal guide type on both sides, single side flat guide type, refuge space type, encrypted horizontal channel type at the entrance and auxiliary tunnel type at the entrance.
