With the continuous improvement of the requirements for digitization and informatization in the field of engineering construction,in view of the problems existing in the application process of BIM (building information model),such as low integration with the site and information interruption at various stages,AR (augmented reality) technology has the function of superimposing models in real scenes.The project BIM+AR visual management platform is built by taking the supporting wharf project of Yantai Port west port area liquefied natural gas (LNG) project as an example.On the basis of building the project electronic sand table and carrying out the basic application of BIM,the application advantages of BIM+AR technology in high pile wharf are explored.Through the comprehensive application of completion simulation,construction guidance,verification and comparison,and progress control etc.It can effectively improve the construction efficiency and fine management level of construction.
