上海市域机场联络线车辆平面布置与疏散仿真研究

Vehicle Layout and Evacuation Simulation Research for Airport Liaison Line of Shanghai Suburban Railway Vehicle

上海市域机场联络线是上海市域铁路线网中第一条新建线路,连接虹桥和浦东两大综合交通枢纽,是国家发改委首批确定的全国11条市域铁路示范线之一。本文首先从机场联络线工程功能定位、线路特征及运营模式等特点出发,详细研究了车辆的平面布置,并根据疏散需求创新性提出车辆下沉式踏步的疏散结构。然后针对新型的疏散结构利用Pathfinder疏散软件建立了机场联络线车辆疏散模型,研究了下沉式疏散踏步结构宽度、贯通道宽度对疏散能力的影响并得出结论。

Airport liaison line of Shanghai suburban railway is the first new line in Shanghai suburban railway network is one of the first batch of 11 national railway demonstration lines identified by the national development and reform commission,which connects the two comprehensive transportation hubs of hongqiao and pudong.This paper starts with the airport liaison line of Shanghai suburban railway engineering function positioning,route characteristics,and operating mode characteristics,and studies the reasonable plane layout of the vehicle in detail.Based on the evacuation demand analysis,it proposes an innovative evacuation structure with sunken steps.Then,Pathfinder evacuation software was used to establish the vehicle evacuation model for the airport liaison line of Shanghai suburban railway.The influence of the width of the sunken evacuation step structure and the width of the passageway on the evacuation capacity was studied and a conclusion was drawn.
