Establishment Method of Extended Data Structure for Digital Twin Water Conservancy and Hydropower Project
In view of the fact that there are many majors in water conservancy and hydropower engineering,the difference of modeling tools will lead to the difficulty of data transfer and even data loss when professional collaboration or phased results are transferred.This paper inno-vatively proposed to extend the original IFC(Industry Foundation Class)data structure on demand,established the extended data structure method of digital twin water conservancy and hydropower engineering,and formed the extended IFC expression method of water conservancy and hydropower engineering for semantic expression,geometric expression and attribute set expression,so as to provide standardized storage space for the easily lost data in water conservancy and hydropower engineering.On this basis,based on Autodesk Revit software,with the help of Revit IFC Exporter open source toolkit,the extended IFC export function including geometric information and attribute information was developed,and the dam structure was extended and exported,which verified the operability of the extended data structure establishment method.Finally,through the data transfer case,it is proved that the method can effectively ensure that the engineering information is not lost during the transfer process.
