针对近年城市内涝灾害频发及损失严重的问题，聚焦排水防涝工程现状，以2016、2020年出现内涝灾害的安徽省六安市为例，系统考虑排水管网与排涝河道的衔接关系，通过追踪管网—内河—外河的雨水外排过程，从积涝点位置对应排水管网达标情况、地面高程与相应受纳雨水河道设计水位关系、河道排涝能力、汇入外河排涝泵站运行条件等方面分析确定造成城市内涝的工程短板。结果表明，六安市老城区积涝点高程具有自流汇入河道条件，排涝河道、排涝泵站均可满足排涝要求，发生内涝的主要工程原因是大部分排水管道标准较低，不能及时将雨水排入河道。在此基础上，进一步考虑老城区排水管道整改实施难度大、周期长，为在整改前尽可能减小内涝风险，提出降低汇入外河口排涝泵站运行水位的新的治理思路及措施，以提高城市排涝减灾能力。

In view of the frequent occurrence and serious loss of urban waterlogging disasters in recent years, this paper focuses on the current situation of engineering of waterlogging drainage, and takes Lu'an City, Anhui Province, which experienced waterlogging disasters in 2016 and 2020 as the research object. Considering the connection relationship between drainage network and drainage channel systematically, the study analyzes and determines the engineering weakness that cause urban waterlogging from the aspects of the standard of drainage network corresponding to the location of water logging points, the relationship between ground elevation and the design water level of the corresponding receiving rainwater river, the drainage capacity of the river, and the operation conditions of the drainage pumping station, based on the tracking of rainwater discharge process of pipe network-inland river-outland river. The results show that the elevation of water logging point in the old urban area of Lu'an City has the condition of flowing into the river by gravity, and the drainage channel and drainage pumping station can meet the drainage requirements. The main engineering reason for the occurrence of waterlogging is that most drainage network have low standards and can not drain rainwater into the river in time. On this basis, it is further considered that the implementation of the drainage network rectification in the old urban area is difficult and long cycle. In order to minimize the risk of waterlogging before rectification, it is proposed to reduce the operation water level of the drainage pumping station at the estuary of the outland river, so as to improve the ability of urban drainage and disaster reduction.
