In order to study the application scenarios of digital twin technology in the “six mechanisms”of safety production risk control in water conservancy projects, this paper conducted a pilot applicationbased on Dianshan Lake shoreline embankment renovation project. The results show that digital twintechnology can integrate real⁃time on⁃site data to quickly search and locate hazardous sources in thesearch mechanism; The risk level can be calculated through the “ direct assessment method” and “ jobcondition hazard assessment method” in the analysis mechanism, and corresponding model componentscan be alerted with colors; In the early warning mechanism, real⁃time monitoring data can beautomatically analyzed, alarms can be triggered, and monitoring videos can be located; Preventivemechanisms can be trained or accident drills can be conducted through program simulations, VR, andother methods; It quickly locates the accident location, disposal plan, responsible personnel, historicaldata and so on in terms of disposal mechanism and responsibility mechanism. The application of digitaltwin technology in the “six mechanisms” of water conservancy engineering is a complex and systematicprocess, which can effectively improve the safety production management level of water conservancyproject,empower and add value to water conservancy project construction.
