城市内涝治理系统设计要点及案例分析

Design Essentials and Case Analysis of Urban Waterlogging Control System

城市内涝治理是一项系统性工程,在对内涝治理特征进行剖析的基础上,提出了达到治理目标的“三步法”,并从源头减排、排水管渠及泵站、河湖水系、应急除险、信息化等方面总结了设计要点,从规划建设、运行维护、应急抢险等方面阐述了管理措施,介绍了几个典型城市的相关案例,为城市内涝治理提供参考和借鉴。

Urban waterlogging control is a systematic project.On the basis of analyzing the characteristics of waterlogging control,a“three-step method”was put forward to achieve the control goal,and the key points of design was sumarized from the aspects of emission reduction at the source,drainage pipe and pumping station,river and lake water system,emergency risk control and informatization,etc.Expounds the management measures from the aspects of planning and construction,operation and maintenance,and emergency rescue,and introduces the relevant cases of several typical cities,so as to provide reference for urban waterlogging control.
