Focusing on the issues of high cost,long cycle,low efficiency of design methods,and high time and labor costs of terrain information data acquisition in traditional terrain measurement and 2D CAD design,this work took an actual engineering as an example,in which GIS and BIM technology were adopted to provide a solution for real-life 3D design of water conservancy engineering.Firstly,a digital image three-dimensional terrain of the Dongzhuang hydro-junction project was constructed,and the actual measurement points of the real model,the accuracy of oblique photog-raphy,and the accuracy of Mesh surface terrain were checked to meet the relevant regulatory requirements.Secondly,BIM real-time 3D visualization application was carried out to complete the calculation of the engineering quantity of the accumulation body near the dam and reservoir section of the Dongzhuang hydro-junction project,the excavation of the upstream cofferdam,and the design of the body shape,providing strong support for project implementation decisions.
