Abstract：Comprehensively improving the digital service level of engineering survey is crucial for accelerating the construction of digital twin in water conservancy.In accordance with the requirements of"demand-driven,application-oriented,digital empowerment,and capability enhancement",it is necessary to deepen the digital mapping,intelligent simulation,and forward-looking rehearsal of all elements in survey production,so as to promote the quality and efficiency of survey and design work,realize digital empowerment,and achieve intelligent early warning and control of geological risks.In view of the current situation in China's water conservancy survey field,where understanding of survey digital twin is not unified,achievements are fragmented,and technical routes are immature,this paper proposes a collaborative mechanism for the whole process of water conservancy engineering survey digital twin,consisting of"digital collection-modeling and simulation-twin application-standard construction".The connotation,application requirements,construction contents,and key technologies of survey digital twin are clarified,and a digital twin platform for water conservancy engineering survey is constructed.The platform includes an"sky-space-earth integrated"data acquisition system,a 2D and 3D real-scene cataloging system,a 3D geological modeling system,a rock slope design system,a"one-map"system for water conservancy engineering survey,and a geotechnical construction management and control system,thereby realizing whole-process digital operations and result delivery.Practice shows that this technology and platform enable dynamic management and control of the entire survey process through digital twin technology,providing a referable solution for digital twin development in the water conservancy industry and supporting the construction of smart water conservancy.
