Study On Emergency Evacuation Simulation In Ancient Town Tourist Attractions

This article chooses the Ciqikou ancient town which is located in Shapingba District,Chongqing as a prototype,through on-site investigation analyzes the potential safety hazard and fire risk of the scenic area itself,and establish a safe evacuation model of the ancient town tourist attraction,by using FDS and Pathfinder simulation software,fire simulation and evacuation simulation analysis of ancient town's emergency evacuation under fire are carried out.The results show that there are many problems in fire safety and safety evacuation,and the ability of emergency evacuation is seriously inadequate.The fire risk analysis and evacuation improvement methods proposed in this paper can effectively reduce fire risk and improve emergency evacuation capability in ancient towns,and also can provide improvement ideas for similar ancient town tourist attractions.The main contents and conclusions of this paper are as follows:(1)Through the actual investigation and the analysis of the risk factors of the ancient town,the comprehensive evaluation index system of the fire risk in the ancient town is established,the fire hazard and emergency evacuation capacity of the street were analyzed.(2)Field investigate the composition of visitors,the proportion of tourists was 40% for adult males,45% for adult women,10% for children,and 5% for elderly people.(3)Use FDS software to calculate the safe evacuation time during the fire in ancient town.It is calculated that the available time shorter is the safe exits 3~6,when the fire source is1,the shortest time for the 3 safety export is 362.8s,when the fire source was 2,the shortest time for the 6 safety export was 118 s.(4)Use Pathfinder software to simulate the emergency evacuation process of street tourists,and get the time needed to evacuate tourists at different times in the street.Among them,2 fire sources were calculated and the longest evacuation time is during the Spring Festival.The respectively longest evacuation time is 1499 s and 1242 s.(5)In the above research,we put forward the improvement measures to improve the evacuation efficiency and strengthen the safety management,so as to achieve the purpose of effectively prevent of the ancient town fire and improving the emergency evacuation capacity.
