Study On Fire Safety Evacuation Of Rescue Station In High Speed Railway Tunnrl

High-speed railway tunnel as a narrow space where due to the chimney effect could have a rapid temperature rise,the decrease of visibility and a large amount of toxic gas when fire occur,the difficulty of rescue would increase.Then,A rescue station which can effectively improve the efficiency,increase the efforts and ensure a safe and orderly evacuation will take important roles in safety evacuation.This thesis combines different aspects in evacuation safety process including psychology and human behavior,several related construction parameters and general project management.Taking the smoke into consideration,the evacuation speed of people was reset to simulate the actual evacuation process.Through Pathfinder simulating,analyzing quantitatively the effect of the points of ignition on the train,the width of evacuation platform,the width of crosschannel protection gate,cross-channel spacing on personnel evacuation,explore the impact of various factors on personnel evacuation and exploring various factors' influence mechanism to personnel evacuation;Based on the most unfavorable principle,carrying out the evacuation simulation about the stop position of the train at the tunnel rescue station,judging whether the most unfavorable conditions meet the safety evacuation criteria and ensure that personnel at rescue stations in high-speed railway tunnels evacuate safely and quickly;using the three factors and four levels orthogonal experiment to analyze the platform width of the rescue station,the width of the protective doors and cross-channel spacing,then finding the combination of parameters with the lowest evacuation time and the most favorable for evacuation,finally using extremum difference analysis to determine the ranking of the three indicator factors for the impact of personnel evacuation.Based on the research methods of existing rescue stations evacuation,considering the influence of flue gas on the safety evacuation of personnel,this thesis studies the interaction of various parameters of the rescue station on the evacuation of personnel,comprehensively analyzes the results of various factors affecting the evacuation of rescue stations,and draws out the relevant design that is most conducive to the safety evacuation of personnel,which provides a basis for the parameter setting of the high-speed railway tunnel rescue station and relevant regulations setting.
