The risk assessment of urban rail transit waterlogging is to determine whether the elevation of the entrance meets the requirements of preventing floodwater from flooding back.Ac-cording to domestic and international standards and experience,the risk of urban rail traffic flood-ing can be evaluated based on whether the elevation at the mouth is higher than the maximum flooding water level of surrounding area plus safety superelevation.Based on practical experience in evaluating related projects,the general process of assessment can be divided into following stages:identification of assessment criteria,information collection and review,initial assessment using model analysis,comprehensive judgement,conformity assessment using identification assessment at station entrance,and recommendation of risk management strategy.
