突发情况下高校教学楼学生疏散行为仿真研究

Simulation Study on the Evacuation Behavior of Students in University Teaching Buildings in Emergency

为了避免高校教学楼突发紧急情况下学生疏散过程中造成人员伤亡,以某高校教学楼学生疏散为研究对象,采用Anylogic仿真平台对突发火灾情况下该教学楼内不同人流水平条件的学生疏散行为进行仿真模拟,并对人流水平较高时的疏散方案进行优化。结果表明,教学楼内学生人数为1500人时,完全疏散需要325 s,不满足安全疏散要求;而增加学生疏散出口宽度和设置疏散向导均可提高疏散效率,将疏散时间减少至300 s内,优化效果较明显。

In order to avoid casualties during the evacuation of students in a university teaching building in an emergency situation,the evacuation of students in a university teaching building was used as the research object,and the Anylogic simulation platform was used to evacuate students with different levels of people flow in the teaching building in the event of a fire emergency.The behavior is simulated and the evacuation plan is optimized when the flow of people is high.The results show that when the number of students in the teaching building is 1500,a complete evacuation requires 325 s,which does not meet the requirements of safe evacuation;however,increasing the width of student evacuation exits and setting up evacuation guides can improve evacuation efficiency and reduce the evacuation time to less than 300 s.The optimization effect is obvious.
