Abstract: 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.
