According to the shortage of scene visual simulation in construction management of navigation power junction project, the concept of information modeling of navigation-power junction is put forward. Based on the technology GIS,3 ds Max and database, a method of navigation power junction project is built, which would make the total factors of navigation power junction virtual realized during the whole life cycle. The method of visualized dynamic information management is confirmed by visualized management system for Yilan navigation power junction, which is constructed on the basis of the engineering data and the technology of GIS.
