Abstract:
According to the on-site investigation and the disaster data of “7·20” Zhengzhou flood disaster in 2021, statistical processing and further analysis of the damage to the residential secondary water supply facilities in the central urban area of Zhengzhou were conducted. Engineering reasons for the disaster were analyzed and summarized, which was based on the recognition of the facilities’ vulnerability and weaknesses during flood disasters. Therefore, this paper can provide references for either reconstructing the existing flood control project or formulation of flood control engineering measures for new secondary water supply facilities.
