摘　　要：近年来极端天气下暴雨致使雨水从交通站点出入口倒灌进入地下轨道的事件频繁发生,不仅严重影响城市轨道交通的运营,还可能引起重大的人员伤亡及经济损失。为保障城市轨道交通不发生积水内涝事件,需精确预测不同降雨条件下城市轨道交通站点出入口的洪涝风险,科学评价出入口抵御洪涝风险的能力。以厦门市某城市轨道交通站点出入口洪涝风险评价为例,采用传统的水文水利分析法进行防洪风险评价,并使用城市雨洪模型进行排涝风险评价,通过水利部门防洪评价与市政部门排涝评价结果对比,探索与思考城市防洪与排涝间的差异,以期为国内外城市轨道交通站点洪涝风险评价提供借鉴。In recent years,heavy rain during extreme weather events has frequently caused rainwater to pour from the entrances and exits of transit stations into underground rail systems.This not only seriously affects the operation of urban rail transit,but may also cause serious casualties and economic losses.In order to protect the urban rail transit systems from waterlogging,it is necessary to accurately predict the flood risks at the entrances and exits of urban rail transit stations under different rainfall conditions,and scientifically evaluate their ability to resist such risks.Taking the flood risk assessment at the entrance and exit of an urban rail transit station in Xiamen as an example,this paper adopts traditional hydrological analysis methods to conduct flood control risk assessments and uses an urban rain-flood model to evaluate flood control risks.By comparing the flood control evaluation results from the water conservancy department with the flood drainage evaluation results from the municipal department,this paper explores and analyzes the differences between urban flood control and flood drainage.The findings are expected to provide guidance for flood risk assessment of urban rail transit stations both domestically and internationally.
