武汉地铁黄浦路站防洪涝水位及预警研究

国内城市地铁防洪已成为轨道交通发展过程中亟待解决的问题,其中防洪涝水位及预警是城市地铁防洪的重点。文章以武汉地铁黄浦路站为研究对象,通过建立暴雨仿真模型,计算得出地铁车站出入口的洪涝积水深度及降雨量阈值,提出基于降雨区间预报的防洪预警方法,针对预警级别提出相应的防洪措施;计算得出黄浦路站3个出入口的洪涝积水水深和降雨量阈值,以及三级预警级别。

Study on flood prevention water level and early warning of Huangpu Road Station of Wuhan metro

The flood control of urban subway in China has become a pressing problem in the development of rail transit,among which the flood control water level and early warning of urban subway are the vital points.In this paper,Huangpu Road Station of Wuhan metro is taken as the study case.Through the establishment of rainstorm simulation model,the depth of flood and waterlogging at the entrance and exit of the subway station and the threshold value of rainfall are calculated,this paper proposes a flood control early warning method based on rainfall sectional forecast,and puts forward the corresponding flood control measures according to the early warning level,calculates the depth of flood and waterlogging and the threshold value of rainfall at the three entrances and exits of Huangpu Road station,as well as the three thresholds of the warning levels.
