Simulation Of The Safe Evacuation Of Load-bearing Personnel In High-speed Railway Station Fire

In recent years,with the popularization of high-speed railways and the improvement of people's living standards,high-speed railways have become the first choice for people to travel in short and medium distances,occupying an extremely important position in national transportation;as a large high-speed railway station built along high-speed railways,its The waiting hall has become an area with large crowds and dense crowds.With the addition of fire,the dense and large number of pedestrians and the psychological activities of pedestrians,the behavioral state has become the primary problem to be solved for safe evacuation work.Under the condition of a sudden fire in the station,some pedestrians will abandon the luggage that they did not want to abandon to survive alone under the condition of being dissatisfied with their moving speed.This situation usually occurs frequently at the evacuation bottleneck,and the abandoned luggage forms a new Obstacles,which greatly hindered subsequent pedestrian evacuation.It is particularly important to investigate the cause of this phenomenon and make corresponding rationalization suggestions for it,and to reduce the cause of this phenomenon to ensure the safe evacuation of passengers in the station.Beijing South Railway Station is China's first modern large-scale passenger transportation hub station that has been completed and put into use.It integrates several transportation modes such as the Beijing-Tianjin Intercity Railway,the Beijing-Shanghai High-speed Railway,the ordinary speed railway,as well as subways,buses,and taxis.All-in-one large-scale transportation hub.This article focuses on the evacuation work of the elevated layer of Beijing South Railway Station,analyzes the factors that affect the psychological activities of evacuees under fire conditions in high-speed railway stations from multiple angles,and analyzes the degree of impact of various factors on the psychological activities of evacuees in accordance with the results of the questionnaire.Fire products will have a greater impact on the psychological activities of evacuees.This paper introduces a quantitative model of individual panic degree to describe the activities of pedestrians during the evacuation process,but the quantitative model of individual panic degree proposed in the existing literature does not consider the fire products.Therefore,the panic degree quantitative model was improved,and the fire products(toxic gas concentration,visibility,temperature)were added to the environmental factors in the model to affect the psychological activities of evacuees.Combining the psychological research results and the fitting results obtained from the questionnaire results,the formula of "panic degree-evacuation speed" is obtained,so as to divide the proportion of unsafe behaviors in emergency situations in different proportions of the population.By using Anylogic simulation software to simulate the evacuation area of the elevated layer waiting area of Beijing South Railway Station,while exploring the existing evacuation bottlenecks in the station,we focused on portraying the evacuation bottlenecks generated by different groups of people during the evacuation process Under the conditions,the impact of abandoned luggage on the evacuation results.It also explores the impact on the evacuation results by exploring ways such as increasing gates,and provides reasonable suggestions for the evacuation of people in high-speed rail stations under fire conditions.
