| Taking small and medium-sized sluices as the research object,based on the Autodesk Revit modeling software under the BIM platform,Revit is redeveloped by using C # language in the development environment Visual Studio.According to the sluice design specification,the visualization forward design technology of small and medium-sized sluice chamber is studied and realized.The creation of sluice engineering parametric family library.According to the drawing collection of practical engineering and the “ sluice catalogue ” in the " typical design atlas of small and medium-sized water conservancy and hydropower projects," the parametric family component library of sluice is created.The size parameters of various components are set,tested,studied and implemented.The realization process of visual model design and parameter interaction.Firstly,the automatic assembly of three-dimensional sluice is studied and realized.Secondly,by writing C # language code and forward design form interface,the user input data and model parameters are read and write bound to achieve the effect of input data driving engineering model change.Finally,the above code abstraction package is connected to the Revit software through the Revit API interface to run.Research and implementation of forward design of sluice visualization.According to the’ sluice design specification ’,the design process is : hydraulic calculation,seepage calculation,lock chamber stability calculation,structural calculation,energy dissipation and erosion prevention calculation by using C # language.The five parts of the calculation method are abstracted and encapsulated,and the Revit API interface is connected to the software to realize the visual and interactive operation process of the whole process of sluice calculation :the real-time output and discrimination of the calculation results,the real-time transmission of the calculation results and the parameters of the three-dimensional model and the size change of the engineering model.At the same time,it also realizes the one-click output of the corresponding drawings and calculation books.Through the research and implementation of the forward design of small and mediumsized sluices based on BIM technology,it not only expands the application of BIM technology in the design of small and medium-sized sluices,but also provides technical reference for other water conservancy projects to use BIM technology for forward design. |
