大型地下客站列车高速越站屏蔽门承压分析

Analysis of Metro Screen Door Pressure on Condition of Train Crossing Large Underground Station in High Speed

以广深港客运专线福田大型地下客站为背景,采用模型试验和三维数值模拟相结合的方法对列车高速越过地下车站时气动效应及屏蔽门承压特性进行研究,得到列车越站速度,屏蔽门间距及通风井设置对屏蔽门承压的影响规律。采用京沪高速铁路的压力波动临界控制标准,模拟得到两种不同车站形式下满足压力波动临界控制标准的屏蔽门设置形式。

On the basis of Futian large underground Station on Guangzhou-Shenzhen-Hongkong passenger transport line,this paper aims at analysis of aerodynamic effect and metro screen pressure by means of model experiments and Three-dimensional numerical simulation,this paper puts forward influence rules of crossing speed,screen door spacing and ventilation shaft on screen door pressure.This paper comes up with screen door spacing that satisfy Beijing-Shanghai high-speed railway critical Pressure standards on two different station forms.
