| 1. | The calculation methods of shelters ’ capacity and the discount method of road capacity under the situation of emergency evacuation were given . then , taking emergency evacuation of the beijing 2008 olympic games as an example , we make out the emergency evacuation preplan for olympic games . on the aid of the advanced computer system simulation techniques , using emergency evacuation simulation software to animate the whole process of olympic evacuation for the fist time , and got some key parameters that can provide decision making supports for decision - makers , such as , the whole evacuation time , the average evacuation speed etc . and the simulation results were analyzed
本文首先分析了我国大城市的交通状况和突发事件发生状况,在分析国内外应急疏散研究现状的基础上,借鉴国内外应对突发事件应急疏散的经验和教训,结合我国大城市突发事件应急疏散的具体特点,提出了大城市突发事件应急疏散研究的总体框架,提出了突发事件应急避难所和应急疏散道路的选择原则,给出了应急避难所的容量计算方法和疏散道路在应急状态下的道路通行能力的折算方法;然后以北京2008年奥运会突发事件的应急疏散为例,制定了奥运会突发事件应急疏散预案,借助先进的计算机系统仿真技术,首次利用应急疏散仿真软件orems对整个疏散过程进行了模拟,得到了总体疏散时间、平均疏散速度等可以为决策者提供决策支持的关键参数,并对仿真结果作了分析。 |
