The Experiment And Study Of Occupant Evacuation Characteristics And Traffic Capacity In Middle-school Building

With the continuous development of a balanced education policy in our country,the public education resources are allocated more equitable and reasonable.It provides powerful supports for a further narrowing of the gap between urban and rural education,a further improvement of educational quality,and a realization of educational equality.At the same time,the lag influences of having middle school safety education and constructing fire prevention facilities have gradually appeared.Teaching building fires and stampede accidents occurred frequently.As a key place of school educational activities,the teaching building has the characteristic of large and crowded.Once it fires or suffers an earthquake,it will cause heavy losses to the personnel safety and public property.Thus,the safe evacuation is a necessary means to protect personnel life safety when emergency events happen.The thesis,taking the three middle schools in Lezhi county of Ziyang city,Sichuan Province as the research object,uses a method which is consisted of document retrieval,questionnaire survey,evacuation drills,numerical simulation and theoretical analysis to make a systematic study of personnel evacuation characteristics and traffic capacity in high-school teaching building.In order to reduce the damage to teachers and students caused by teaching building fire,help more students to escape safely in a fire,and improve the stability of campus fire safety,the thesis takes the thoughts of evacuation experiment and computer numerical simulation as guidance,and studies safety personnel evacuation in the situation of teaching building fire.Its purposes are to provide reliable basis for developing emergency evacuation plans and evacuation disaster prevention strategy.The key points and conclusions are as follows:1.Through questionnaires to assess the state of Fire safety education in middle schools,find out the main reasons that impact the education quality and effect.The thesis analyzed students’ psychological and behavioral characteristics in the process of teaching building evacuation.2.Make sure that seat distribution of students has a markedly impact on the evacuation speed of the building worker.According to analysis,the type 222 classrooms are the fastest in evacuating,while the type 333 classrooms at a moderate speed and the type 252 classrooms the slowest.3.Analyzing the evacuation experiment data,we calculate that the average locomotion velocity in the corridor of the building worker’s evacuating students,that is,the movement speed range of the building worker’s evacuating students is 0.03～4.8 meters per second.The average of all movement speed is 1.06 m/s.4.To evacuate safely,the middle school building worker has an action time range of 5.32～43.25 seconds.5.To testify that Pathfinder is effective in assessing building worker’s safe evacuation.
