道路转角对人员疏散的影响与分析

在封闭建筑和开敞空间的道路设计中,常常忽略道路转角对人员疏散的影响。目前有关道路转角对人员疏散影响的研究多是定性分析,然而对于人员高度聚集的场所,任何细小的疏忽都会导致在火灾和人为灾害疏散过程中的拥堵,甚至造成严重的事故。因此,道路转角对人员疏散的影响不容忽视。本文借助人员疏散仿真软件S IMULEX,定量分析了道路转角对人员疏散的作用,获得了一些规律性的认识,并针对步行道路转角的设计给出了一些建议。

The Analysis of Corner Effect on the Occupant Evacuation

In the evacuation route design of enclosed buildings and open spaces,the influence of the angle of corners on the occupant evacuation is generally ignored and only a few qualitative results on the corner effect have been given in literatures.However,in order to avoid possible fatality caused by evacuation congestion in any emergency event,such as fire or terrorism attack,the corner effects should be carefully and thoroughly researched,which is just the purpose of this paper.With the help of SIMULEX,the influence of corners of different angles on the evacuation is quantitatively studied and some general knowledge on the corner effect laws are obtained and some suggestions on the improvement of occupant evacuation route design are proposed as well.
