城市轨道交通车站及正线防汛减灾策略研究

Analysis on flood control and disaster reduction strategy of urban rail transit stations and main railway-lines

针对近年来城市区域性暴雨洪涝等极端天气常发的态势,研究分析地铁车站及正线发生水淹事故的原因并提出具体防汛准备和应急策略,包括地铁车站出入口的高度设计要合理并配备相应防汛物资,具备应对站外积水的挡水能力;地上停车场(库)到地下轨道正线之间设置挡水墙和驼峰段并重点监管;地铁车站应明确工作职责,强化风险管理、搭建预报、预警、预演、预案“四预”管理平台,依靠智慧化防汛手段建立健全科学、规范、严谨的地铁防汛应急处置流程等。研究旨在为城市轨道交通车站及正线防汛减灾工作提供参考意见。

In view of the frequent occurrence of extreme weather events such as urban regional rainstorms and floods in recent years,this paper focuses on studying and analyzing the causes of flooding accidents in subway stations and main rail lines,and puts forward specific flood control and disaster reduction strategies.The reasonable height design standard of subway station entrances and exits,and the Flood preparedness materials to deal with the ponding outside the station.A water retaining wall and a hump section shall be set between the ground parking lot(garage)and the main line of the underground track and shall be subject to key supervision.Urban rail transit stations should clarity their responsibilities,strengthen risk management,build a FEDE(forecasting,early-warning,drilling and emergency plan)management platform,and rely on intelligent flood prevention measures to establish a sound,scientific,standardized and rigorous emergency disposal process for subway flood prevention.The purpose of this study is to provide reference for the design and planning of urban rail transit stations and main lines for flood control and disaster reduction.
