Research On 3D Modeling And Application Of Model Information In Dashijian Reservoir

Since the popularization of Building Information Modeling in China,this technology has exerted a great influence on the traditional Building industry,improving the way of Information storage,improving the way of communication among project participants,and achieving rich research results in the construction field.With the continuous development of water conservancy industry,its engineering construction concept is also developing towards the direction of information integrated management,and BIM technology happens to meet this demand.By building BIM engineering information model,it integrates various information generated in the whole life of the project,including design,construction,operation and maintenance,and provides a large amount of data basis for information management.Aiming at the problems of low efficiency of building BIM information model for water conservancy engineering and the difficulty of its extended application,this paper adopts parametric modeling and secondary development and utilization of the built model by taking the material partition of concrete gravity dam as the condition of modeling.The main research work is as follows:(1)Combining the characteristics of water conservancy engineering and BIM technology,the application value of BIM technology in each stage of the whole life of water conservancy engineering construction is analyzed.Compared with the existing mainstream BIM software,this study selects Revit of Autodesk company as the core modeling software,and proposes the basic process of information model construction;(2)According to the characteristics of water conservancy projects,the concrete gravity dam components are classified,and the parametric modeling of each component in the dam section is studied.The interactive design of Civil3 D software and Revit is carried out to generate the terrain digital model.At the same time,based on the optimization of BIM technology in construction management,the construction model is simulated by combining Navisworks software and schedule plan.(3)By summarizing the API that satisfies the secondary development of hydraulic engineering,the secondary development of Revit software is studied based on the development process,and the engineering information of components in the model can be extracted,and the budget estimate table can be compiled by bill of quantities.Meanwhile,the application interface is expanded by means of external application of Revit API,and the functional commands of related applications are realized.
