Aiming at the difficulty in ensuring the modeling accuracy and efficiency of BIM technology in the application of high-pile wharf in inland rivers,Visual Studio 2017 is adopted to carry out secondary development on Bentley′s Microstation graphics platform through development methods such as C++,C # (Addin),and C++/CLI mixed programming,and a BIM software module suitable for parametric design of pile foundation in high-pile wharf in inland rivers is developed.The module includes functions such as automatic design of the platform grid for high-pile wharf,creation of grid plan,preview of graphics and models,parametric modeling of pile foundations,import and export of pile foundation parameters,and summary of pile foundation parameter tables.By intuitively inputting the required parameter set for model creation,high-precision and high-efficiency parametric 3D design of pile foundations is realized,thereby simplifying the process of creating a type of model and reflecting the application advantages of BIM technology in parametric design,model visualization and statistical engineering quantity.
