Analysis Of Crowded And Trampling Accidents In Public Places And Research On Prevention And Control Measures

With the continuous improvement of people’s living standards,in order to meet the needs of more people,public events are constantly increasing and improving.However,due to the high density of people in public places and the long-term evacuation,it often leads to crowded stampede accidents.Therefore,the study of crowded and trampling accidents in public places is particularly important.Scholars at home and abroad have conducted certain research on the study of crowded and trampling accidents in public places.Foreign scholars mainly use computer modeling to study the behavior of crowds.Domestic scholars mainly introduce "social power" on the basis of foreign countries to carry out model research on crowd evacuation behavior.At present,few scholars have studied the causes and countermeasures of crowded stampede accidents.This paper aims to analyze the influencing factors of crowded stampede accidents and propose corresponding countermeasures based on the analysis results.This paper firstly counts the cases of crowded and trampling accidents at home and abroad from 2008 to 2017,and analyzes the space,time,evolution process,main factors and accident characteristics of the accident;then carries out detailed analysis according to the main factors of the accident.A multi-level fuzzy comprehensive evaluation model is established,and the weights of each evaluation index are determined by the combination of AHP and accident factor normalization.Later,a gymnasium is used as the research object,and the multi-level fuzzy evaluation model is used for analysis and research.Corresponding countermeasures have been proposed for the influencing factors that lead to crowded stampede accidents,and some suggestions for public event venues to avoid the occurrence of crowded stampede accidents.
