摘要
解决城市轨道交通运营过程中在大客流扰动下的安全问题.首先,用仿真模拟分析并比较城市轨道交通在大客流扰动下的脆弱性.运用MATLAB仿真模拟,编写程序代码并运行程序得出结果.选北京地铁1号线的车站作为分析与模拟的对象,并设置模拟系统的参数,每个地铁车站进行2次模拟.通过专家座谈、现场问卷调查和实地调研得到大客流扰动下城市轨道交通脆弱性分析的基本数据.通过MATLAB对基础数据进行处理,得到北京城市轨道交通大客流扰动下1号线站点脆弱性指标的得分.对得分进行归一化处理,并将归一化后数据带入突变理论模型中,得到在大客流扰动下城市轨道交通的暴露度、敏感度、适应度和脆弱性值.结果表明,北京城市轨道交通1号线在大客流扰动下,大望路站的脆弱性最高,东单站的脆弱性适中,军事博物馆站的脆弱性较低.
In order to solve the safety problem of the interruption from larger passenger flow during the course of urban mass transit operation,the article firstly analyzed and compared the vulnerability of urban railway system under the interference from large passenger flow with analogue simulation.It wrote program code and ran program to obtain the result by utilizing MATLAB analogue simulation and set the parameter of simulation system by taking station of Beijing Subway Line 1 as the object of analysis and simulation.2 simulations were carried out for each metro station and achieved escape number and average escape personnel waiting time models in each simulation process.Secondly,the score of vulnerability index in Subway Line 1 under the interference from large passenger flow of urban rail transit in Beijing was obtained by the basic data obtained from the analysis on urban Rail Transit Vulnerability under the disturbance of large passenger flow from expert discussion,on-the-spot questionnaire survey and field investigation,and the primary process of basic data with MATLAB.The value of urban rail transit exposure,sensitivity,fitness and vulnerability under the interference of large passenger flow was obtained by introducing the normalized data into catastrophe theory model after integrating on the score.The conclusion of MATLAB simulation was identical as that after questionnaire and expert discussion then calculation:the sequencing of vulnerability of Dongdan station,Dawanglu station,and Military Museum Station of Beijing Urban Rail Transit Line 1 under the interference of large passenger flow showed the maximum Dawanglu station,medium Dongdan station,and lower vulnerability Military Museum Station.
