Embodiment 1

[0048] 1. A site selection method for an extra-long railway tunnel emergency rescue station, characterized in that the method comprises the following steps:

[0049] S11. Read the site selection impact parameters, the site selection impact parameters include: the time from the beginning of the fire to the development of a dangerous state, the time to get off and evacuate, the average speed of the train running from the fire site to the rescue station, and the braking of the train distance;

[0050] S12. Construct the calculation model of the maximum setting distance of the rescue station with the read site selection influence parameters, and calculate the maximum setting distance of the rescue station;

[0051] S13. Read the site selection decision parameters. The site selection decision parameters include: the maximum setting distance, the number of rescue stations to be set, the number of alternative rescue stations to choose from, the construction cost of each alternative r...

Abstract

The invention relates to the technical field of railway construction design, in particular to a site selection method and system for an emergency rescue station in a super-long railway tunnel. Including the following steps: S11. Read the site selection constraint parameters; S12. Construct the maximum setting distance calculation model of the rescue station, and calculate the maximum setting distance of the rescue station; S13. Read the site selection decision parameters; S14. Build the site selection model , calculate the optimal location scheme through the location model. The present invention analyzes and obtains the maximum setting distance of adjacent emergency rescue stations of tunnels based on different line types and train types, so that the calculated maximum setting distance of adjacent emergency rescue stations is more suitable for actual lines. The present invention comprehensively considers the route conditions, operating vehicle types, the positions of the candidate points of the rescue station, the distance between the candidate points, the construction cost of the emergency rescue station, etc., the modeling process is convenient and simple, the modeling standard is unified, the calculation efficiency of the method is high, and the method is true and reliable , the method considers all factors and has good operability, versatility and reusability.

Description

technical field [0001] The invention relates to the technical field of railway construction design, in particular to a site selection method and system for an emergency rescue station in a super-long railway tunnel. Background technique [0002] Tunnel group is a group of tunnels whose distance between adjacent tunnel openings is less than the length of a passenger train. There are three types of accidents in tunnels. Hot accidents: fire, explosion due to fire, release of toxic fumes or gases; cold accidents: crash, derailment; sustained shutdown. [0003] Research shows that compared with derailment and other cold accidents, the super-long railway tunnel is pipe-shaped, with narrow space, rapid fire spread, difficult smoke exhaust, poor visibility in the tunnel, and confusing sense of direction. Evacuation and rescue are difficult. The "International Union of Railways Regulations" also believes that the main dangers in the tunnel are fire, collision and derailment. Due ...
