Research On The Ability Of Earthquake Emergency Evacuation Of Teaching Staff

As social wealth accumulates,people pay more and more attention to life and property.Since the 20 th century,there have been nearly 800 earthquakes of magnitude 6 and above in China,covering all provinces,autonomous regions,and municipalities except Guizhou,Zhejiang,and the Hong Kong Special Administrative Region.Therefore,relevant domestic scholars attach great importance to the improvement of building seismic design methods and the improvement of specifications,but there is relatively little research on the emergency behavior of disaster victims in different environments and the evacuation ability of affected buildings in earthquakes.In the environment of sudden disasters,when the people in the restricted space are relatively dense,a series of serious consequences such as detention and congestion may even occur during the evacuation process.Once an accident occurs,it will not only be the misfortune of the families of the victims,but will also cause widespread concern in society.The importance of public safety risk prevention and control work has become increasingly prominent,and the problem of emergency evacuation capabilities of personnel has therefore become an important and urgent research topic.Based on the serious disasters that have occurred in frequent earthquakes in recent years,this paper studies the problems of most building buildings in colleges and universities due to their age,which is prone to local collapse during earthquakes,hindering emergency evacuation routes and affecting the escape of internal personnel.After consulting the relevant design materials,this article constructed a three-story teaching building structure as authentically as possible,and configured pedestrian locations for the initial environment according to the actual teaching needs and the requirements of the corresponding research materials.Considering factors such as rational and irrational choices,conflict resolution,the relationship between the ideal evacuation speed and the actual evacuation speed,and renewal principles,the pedestrian walking method is established.By comparing the characteristics of the current multiple theoretical models of emergency hedging statistical physical model,combined with the simulation scenario,an improved cellular automaton model theory is selected to simulate the evacuation model of the teaching building under earthquake.Through visual numerical simulation,the development process of three congested areas in the simulation environment,including the classroom exit area of each classroom,the middleplatform corner of the main staircase between the second and third floors,and the corner of the main staircase of the second floor hall,was analyzed.Simulation results such as changes in pedestrian flow,changes in the number of pedestrians staying in place,changes in the average speed of pedestrians,and evacuation time,and compare the emergency evacuation capabilities of various heavily congested areas with respect to the three relative positions,two size directions,and three earthquake durations.The sensitivity of time measures the impact of various damages on the emergency evacuation of internal staff under the earthquake.Combined with the actual situation of the project,some evacuation suggestions were put forward from three aspects: the advancement of earthquake prevention and mitigation work,the decision-making when an earthquake occurs,and the publicity and education of public emergency avoidance.
