Study On Fire Safety Evacuation During The Grand Theater

With the rapid development of China’s urbanization process,in order to meet people’s multi-level,multi-faceted social demand and improve economic efficiency,the theater building is highly concentrated in large space,functional diversity,complex building structures,people came into being,they are crowded places.When the safe evacuation facilities are not complete or mismanagement,in the event of fire or other emergencies,it is prone to group death and crowded stampede,so the most prominent of the safety problem of these places is peopel how to safely,rapidly and orderly for evacuation,as well as an important duty of the government and public department.Therefore,research on safety evacuation of the grant theatre,it is good to improve the safety of the theater building,provide a theoretical basis for designers,and provide reasonable suggestions for the operation and management of the emergency management department.First,this paper analyzes the fire risk according to the characteristics of the grand theater,briefly introduces the basic theory of evacuation and calculation method of personnel evacuation time;analyze the factors that affect the safety of theater evacuation time,namely the internal structure of the building,human factors,emergency evacuation management,the fire environment.Second,based on crowed theory and Pathfinder software simulation to study the effect of exit width on the grand theater evacuation time.In order to study the influence of various factors on the safety evacuation of the theater,7 evacuation scenarios were set up,and then the simulation data were obtained by Pathfinder.Final,the total evacuation time and average people evacuation time two indexes as reference,using the grey relational analysis method to analyze the factors of the evacuation time.The grey comprehensive relational analysis method and the grey point relational analysis method were used to calculate the grey correlation between each influence factor and the conclusion.According to the above,the paper puts forward some countermeasures for the safe evacuation when the grand theater fire.
