城市道路用于大排水系统的规划设计方法与案例

摘要

In recent years,the important role of major drainage system in urban flooding mitigation have been increasingly recognized.As an important part of sponge city development,the planning and design methods of major drainage system has been lacking.Further combed the definition and composition of major drainage system,also its relationship with related subsystem of Sponge City,the planning and design methods of major drainage system and overland roadway paths was proposed.On the base of the case,the designing of roadway overland flow paths was introduced,so as to provide reference to the construction of major drainage system in our country.%近年来,大排水系统在城市内涝防治中的重要作用得到越来越多的认同,作为海绵城市建设的重要内容,我国仍然缺乏大排水系统的具体规划设计方法.进一步梳理了大排水系统的概念、构成及其与海绵城市相关子系统的衔接关系,提出了大排水系统的规划方法与地表径流行泄通道的设计方法,并以某城市片区内涝防治系统构建为例,通过案例介绍了道路径流行泄通道的设计,以期为我国大排水系统的合理构建提供参考.
