Abstract：The national 14th Five-Year Plan and the National Water Network Construction Plan Outline explicitly propose the implementation of major national water network projects and the accelerated construction of the national water network.A key task of this construction is to focus on ensuring urban water supply safety,enhancing the assurance rate of urban water supply,and overcoming the"water"bottleneck restricting urban development.Shenzhen,as a pioneering demonstration zone of socialism with Chinese characteristics,a national special economic zone,and a core city in the Guangdong-Hong Kong-Macao Greater Bay Area,has a permanent population of nearly 20 million,making its water supply safety particularly critical.Taking the newly constructed Gongming Reservoir-Qinglinjing Reservoir Connection Project and the Luotian Reservoir-Tiegang Reservoir Water Conveyance Tunnel Project in the"three vertical and four horizontal"water network system of Shenzhen as the background,this paper,from the perspective of survey and design,systematically investigates the key technical issues that must be addressed in the construction of water networks in megacities.These include safety control in long-distance deep-buried tunnel exploration,engineering route and site selection and type determination,maintenance and operation,major structural design,and multi-objective coupled smart water network dispatching during the operation stage.A full-chain systematic study is carried out,and integrated solutions are proposed to facilitate smooth project construction and intelligent operation,thereby enhancing the"water"resilience of urban development.
