摘要
选取步行速度、人群组成、疏散人数、人员疏散预动作时间、出口熟悉程度、避让策略、出口宽度设计7因素2水平正交试验,采用Pathfinder对广州某地铁站站厅层和站台层的人员疏散运动过程进行模拟,开展城市轨道交通应急疏散影响因素研究。通过对试验结果进行极差分析得出各因素对疏散时间影响程度的排序,利用方差分析将各因素对疏散时间的影响分为显著、比较显著、不显著。根据分析结果得到"可能最优的疏散方案",提出保障人员疏散可采取的措施。
The orthogonal experiment with 7 factors 2 levels was designed with factors of walk speed, group composition, evacua- tion number, pre-action time of person evacuation, familiar de- gree of exits, avoidance strategy and width of exits. Pathfinder was used to simulate the evacuation process of people on the platform floor and station hall floor in a subway station in Guangzhou. The influence factors of emergency evacuation of city rail transit were researched. The order of influence on the evacuation time by each factor was obtained by range analysis on experiment results,and the influence of each factor on the evac uation time was divided into obvious, relatively obvious and not obvious by variance analysis. The possible optimum evacuation scheme was obtained according to the analysis results and the measures to ensure the sa{ety of evacuation people were put forward.
