摘要
为推进我国海绵城市全域化建设,在生态化内涝防治基础上,根据城市景观河道的滞蓄能力,将其周边一定区域内的超标雨水径流输送至河道进行生态滞蓄,从而达到缓解城市排水系统压力的目的。详述城市景观河道海绵系统的构建方法、生态滞蓄能力的核算方法与雨水调控路径的设计方法,并以雄安新区D1组团R10河道项目为实践案例辅助剖析,旨在为生态化内涝防治研究提供参考。
In order to promote the global construction of sponge city in China,on the basis of ecological flood prevention and control,according to the retention capacity of urban landscape river channel,the excessive rainwater runoff in a certain area is transported to the river channel for ecological retention,so as to relieve the pressure of urban drainage system.The construction method of sponge system in urban landscape river channel,the calculation method of ecological retention capacity and the design method of rainwater regulation path are described in detail,and the D1 group R10 river project in Xiong’an New Area is taken as a practical case to assist analysis,aiming to provide reference for the research of ecological flood prevention and control.
