摘要/Abstract

摘要： 为提高地铁站突发事件人群疏散效率,构建融合人-环特征的地铁站人群疏散速度修正模型。首先从人员、环境2个方面,分析地铁站突发事件疏散设计要求及人群疏散影响因素,选取地铁结构、携带行李等8个速度影响因子,建立速度影响指标体系;然后采用未确知测度理论,计算速度指标熵值,确定速度修正量值;最后以某地铁站火灾事故为例,修正人员移动速度,设置疏散个体参数,仿真地铁站火灾疏散过程。结果表明:速度修正前地铁站疏散仿真总时间为264.0 s,修正后疏散总时间为337.0 s,仿真修正后的疏散时间更长,人员危险性更大。

Abstract: In order to improve the efficiency of crowd evacuation in subway accident, a model taking human-environment factors into account was built for correcting speed of evacuation from subway stations. Before building the model, emergency evacuation design requirements of subway stations and factors affecting the crowd evacuation were analyzed from two aspects of human and environment. Eight factors influencing the speed, such as the subway structure, carrying baggage and others, were identified, and an index system was established for evaluation of the effect on speed. The entropy values of speed indexes were calculated to determine the speed correction value using the unascertained measure theory. The model was applied to a fire accident in a subway station in Xi'an city, for which a simulation of crow evacuation was made. The results show that the total time of evacuation simulated is 264.0 s before the speed correction, and the total time of evacuation after speed correction is 337.0 s,that is to say correction makes the evacuation time longer and the personnel risk greater.

Key words: emergency evacuation, speed correction model, uncertainty measure, factor influencing speed, subway station
