摘要:

针对我国城市道路排水系统应对降雨时存在的排水路径不明、系统分工不清、实施效率不高等问题,解析了城市道路排水系统应对各阶段降雨时的控制机理和径流排放路径,给出了北京市城市道路排水系统应对降雨的“防湿鞋”“防积水”“防内涝”能力阈值,并结合监测预警系统和应急抢险措施,提出了“防失控”能力建设措施。从系统的顶层规划设计、综合排水能力、应急管理能力3个层面,提出了城市道路排水系统的提升策略。

关键词:城市道路排水系统;能力阈值;监测预警;建设策略

Abstract:

In response to issues such as ambiguous drainage paths, unclear system division of responsibilities, and low implementation efficiency in urban road drainage systems when handling rainfall in China, the operational mechanisms of the urban road drainage system, as well as the discharge pathways of runoff, were thoroughly analyzed. The capacity thresholds for Beijing’s urban road drainage system to manage rainfall in terms of preventing wet shoes , preventing waterlogging , and preventing flooding , are established. In conjunction with the monitoring and early warning systems, as well as emergency rescue measures, construction guidelines for enhancing the system’s out-of-control prevention capacity are proposed. Improvement strategies for urban road drainage systems are proposed from three perspectives: top-level planning and design of the system, enhancement of comprehensive drainage capacity, and construction of emergency management.

Key words:urban road drainage system; capacity threshold; monitoring and early warning; construction strategies
