摘　　要：抽水蓄能电站的建设通常位于植被茂密、人迹罕至的山区,给传统的控制点选点作业带来了巨大挑战,外业劳动强度大、方案可靠性低、作业安全风险高。基于多源数据融合构建真实地形级三维模型的可视化场景,消除了植被覆盖的影响,实现了施工测量控制网选点的三维可视化设计。通过2个抽水蓄能电站实际工程施工案例分析,在无需外业踏勘的情况下,就可以基于GIS方法进行判断点间通视、点间距离量测、水准路线选择和是否便于施工测量放样等前期设计分析,地形级三维模型可视化设计提高了作业效率,同时也保证了控制网设计符合规范要求。Typically,building pumped-storage power stations in densely vegetated and hard-to-reach mountainous regions present significant challenges to the conventional technique of selecting control points.These challenges include high physical exertion in-field,low solution reliability,and increased operational safety risks.This paper constructs a visualization scene of a real-life,terrain-level 3D model using a fusion of data from multiple sources,which can effectively remove the impact of vegetation cover,thereby facilitating a 3D visualization design for the construction survey control network.The application of the proposed method in two pumped-storage power stations shows that this research can undertake an initial design analysis including assessing between-point perspectives,measuring point-to-point distance,choosing the horizontal path,and determining suitability for construction measurement and lofting,without field surveys.This approach offers significant ease and assurance that the control network s design complies with specification requirements.
