选取东北地区某片区为研究区域,利用InfoWorks ICM软件建立一维/二维耦合城市内涝模型.模型模拟结果显示,在1年一遇、3年一遇、5年一遇、10年一遇、20年一遇、30年一遇的设计降雨情景下,研究区内均有超过50%的排水管网处于超负荷状态;在3年一遇降雨的标准下,研究区雨水管网排水能力达标率仅有27.7%;在30年一遇的设计暴雨情景下,研究区域内多处产生严重积水,积水深度最高达1.2 m,城市内涝高风险区主要位于八面通街和乌苏里路附近.为提高城市内涝应急管理效率,在内涝风险等级评价的基础上提出城市内涝智慧化管理方案,可为城市应急管理部门防涝管理工作提供参考.
In this paper,an area in the northeast region is selected as the study area,and a 1D/2D coupled urban flooding model is established using InfoWorks ICM software.The model simula-tion results show that under design rainfall scenarios with return periods of 1 year,3 years,5 years,10 years,20 years,and 30 years.,more than half of the drainage network in the study area is overloaded.Under the standard of 3 years,the drainage capacity of the study area is only 27.7%.Under the 30 year design storm scenario,severe waterlogging occurs in many places in the study area,with a maximum waterlogging depth of 1.2 m,and the high-risk areas for urban flood-ing were mainly located in the vicinity of Bamiantong street and Ussuri road.In order to improve the efficiency of urban flooding emergency management,this paper proposes an intelligent man-agement program for urban flooding based on the evaluation of flooding risk level,which can pro-vide a reference for the urban emergency management department to prevent flooding manage-ment.
