数字孪生丹江口工程建设关键技术研究OA

The Danjiangkou Water Control Project is the core water source for the Middle Route of the South-to-North Water Diversion Project and faces major management challenges,including complex dam structures,pronounced water-quality stratification,and frequent geological hazards along the reservoir banks.Digital twin of Danjiangkou Water Control Project,as one of China's national pilot digital twin water conservancy projects,this study established a coupled basin-project dispatching system with two-way feedback.Focusing on three major safety scenarios-dam safety,water quality safety,and geological hazards in the reservoir area-the study advanced key technologies for the"Four Pre"functions of forecasting,early warning,rehearsal,and contingency planning and developed a suite of models,including multi-physics coupled finite element simulation of dam behavior,three-dimensional hydrodynamic and water-quality simulation for deep reservoirs,and multifactor intelligent landslide early warning.Following operational testing during the 2023-2025 flood seasons,impoundment to a water level of 170 m,and sudden water pollution incidents,digital twin of Danjiangkou Water Control Project platform enables intelligent project safety assessment and emergency risk response.The study establishes a digital twin development model for large-scale water diversion hubs and provides a replicable technical approach to the intelligent management and control of the national water network.
