紧急制动状态下大学校园教学楼疏散系统分析研究

ANALYSIS AND RESEARCH ON EVACUATION SYSTEM OF UNIVERSITY CAMPUS TEACHING BUILDING UNDER EMERGENCY BRAKING

本文使用截面流量法对长安大学明远一区教学楼各疏散口不同类别、不同时间的双向运动流量进行统计,并使用依托消防疏散模拟软件Pathfinder进行疏散模拟。结果表明:校园教学楼设计需要注意疏散楼梯布局和不同方向疏散口的宽度与开放程度,设计时改变疏散楼梯可以有效降低疏散时间,增加疏散口可降低单一疏散口的人流密度。

In this paper, the cross-sectional flow method is used to count the two-way movement flow of different types and different times of each evacuation exit in the teaching building of Mingyuan district of Chang’an University, and the evacuation simulation is carried out by using the fire evacuation simulation software Pathfinder. The results show that the design of campus teaching building needs to pay attention to the layout of evacuation stairs and the width and opening degree of evacuation ports in different directions.Changing the evacuation stairs in the design can effectively reduce the evacuation time, and increasing the evacuation outlet can reduce the flow density of a single evacuation outlet.
