Abstract
The geographical and climatic environment of the railway network is complex and changeable.Especially during the flood season,heavy rainfall causes serious interference to the normal operation order of trains,which puts forward higher requirements for the response to flood control safety risks in railway traffic.The fishbone diagram analysis method was adopted,and the 5M1E management tool was utilized to systematically identify flood control safety risks.The probability risk assessment model P=g(R,L)was applied to quantitatively evaluate risk events,and a four-level flood control safety risk assessment matrix was obtained to classify and control the identified flood control safety risk items.To deal with the impact of various risk events on railway traffic organization during the flood season,risk assessment response strategies in four aspects were proposed,including risk investigation and governance,traffic dispatching response,passenger service adjustment,and emergency event response.A three-level rainfall warning and handling process covering roles such as train dispatchers,station duty officers,drivers,equipment management units,and station and depot command centers was constructed.The start time limit and management requirements for the four-level early warning response of railway traffic were proposed.This paper provides a reference for the flood control work of railway traffic stations and depots.关键词
