Abstract: Digital twin water conservancy project is the core and key to smart water conservancy construction. In view of the safe operation requirements of water conservancy projects, it is necessary to combine digital twin with safety analysis and early warning technologies to enhance the safety level of project operation and the ability to deal with emergencies. We introduce the overall framework of intelligent safety analysis and early warning technology based on digital twin platform. In particular, we elaborate on the perception system and model library of engineering safety monitoring. The intelligent platform has functions of monitoring and prediction, early-warning and alarming, risk simulation, and intelligent emergency responses. At present, the platform has been preliminarily applied to the digital twin construction of Jiangya and Zaoshi project, and is expected to offer reference for the construction of similar digital twin projects.
