摘　　要：为实现数字孪生万家寨水库冰凌发展过程模拟预演功能,将BIM、倾斜摄影等模型与GIS场景进行多源地理空间数据融合,构建万家寨库区全要素数字化场景。基于水库回水区水-冰动力耦合模型预报预警计算结果,将地理空间、气象水文、凌情预报等数据与水库回水区冰水动力学数学模型进行耦合计算,模拟水库水位、流量、表面冰、地形等不同组合条件对冰凌堆积的作用。通过冰水动力学理论和虚幻引擎+GIS引擎融合的方式,将冰凌发展过程数据在模拟仿真场景中进行预演,实现将水库回水区冰凌发展过程二维模拟数据在数字孪生三维场景中的映射与表达,为万家寨库区防凌调度“四预”功能提供高水平信息化支撑。In order to achieve the simulation and preview function for the development process of ice in the digital twin Wanjiazhai Reservoir,multiple geographic spatial data sources,such as BIM models,oblique photography models,and GIS scenes,were integrated to construct a fully digital scene of the Wanjiazhai Reservoir area.Based on the forecast and early warning results of the water-ice dynamic coupling model in the reservoir backwater area,geospatial,meteorological,hydrological,and ice forecast data were coupled with the mathematical model of ice-water dynamics in the reservoir backwater area to simulate the effects of different combination conditions of reservoir water levels,flow rates,incoming ice,terrain,and other conditions on ice accumulation.Through the integration of ice-water dynamics theory and the Unreal Engine+GIS Engine,the data on the ice development process were previewed in the simulation scene.The mapping and representation of 2D simulated data on the ice development process in the digital twin 3D scene were achieved.This study provides high-level information support for the“Four Pre”function of anti-ice dispatching in the Wanjiazhai Reservoir area.
