我国北方平原城市社区内涝防控设计方法

Design Method for Flood Control in Urban Communities in the Northern Plains of China

近年来我国城市暴雨灾害频发,社区作为城市重要的组成单元,面临着内涝灾害的侵袭。针对当前内涝防治体系不完善的问题,简要分析城市社区现状内涝灾害特点与防治方法,总结现状防涝体系存在的局限性,从排水角度构建基于微排水、小排水、大排水系统的内涝防治体系,建立基于场地高程、地形坡度、挡水阻水的内涝防控方法,形成包含设计要点、设计流程、设计图示及关键设计参数的城市社区内涝防治设计方法体系,为新时期海绵型城市社区的规划设计提供参考与借鉴。

In recent years,urban rainstorm disasters have occurred frequently in China.The community,as an important component of the city,is exposed to urban flooding.In view of the imperfection of the waterlogging prevention and control system,this paper briefly analyzes the characteristics and prevention methods of urban flooding,and summarizes the limitations of the current system.A waterlogging prevention system based on micro system,minor system and major system is constructed from a drainage perspective.The waterlogging prevention and control methods based on site elevation,terrain slope,and water-retaining measure is established.A design method system including design points,design process,design diagram,and key design parameters is formed,which provides reference for the planning and design of sponge communities in new era.
