Research On BIM Modeling Technology Of Hydraulic Structure In Planning Stage

The world into the digital and information age,China 's water conservancy construction urgently need to improve the level of water conservancy information.BIM technology provides a lifecycle platform for water conservancy projects,enabling the collection,delivery and sharing of engineering information.And provide effective support to the whole life cycle of water conservancy project by virtual reality technology.In this paper,the combination of BIM technology and virtual reality technology,through the water conservancy project parameterization to establish a digital model,and rely on virtual reality system for water conservancy projects in all directions,highlighting the water conservancy project in the information age transformation and upgrading.The main research results are as follows:(1)Based on the concept,characteristics and core technology of BIM technology and virtual reality technology,the paper analyzes the application prospect of two technologies in water conservancy project.(2)Based on the Autodesk Revit software based on the BIM technology platform,a parametric digital model was established for hydraulic engineering structures and geological structures.(3)The terrain and hub area terrain are modeled based on Google Earth data and ASTER GDEM data,respectively.(4)Use 3DS Max for large scene layout,and give the model texture map,and then rendering and baking work.(5)Using Quest 3D platform to design the virtual reality system of water conservancy project,and to complete the project information introduction,roaming system and other functions.
