基于BIM技术的边坡地质建模与有限元分析

Slope Geological Modeling and Finite Element Analysis Based on BIM Technology

  • 摘要: 本文通过BIM技术与有限元分析软件的结合,建立边坡的三维地质模型并进行稳定性分析。使用Revit应用程序接口,结合Kriging插值法开发一款具有空间插值功能的插件,并运用插件对地质数据实现地质模型的精细化建模。模型通过几何转换接口导入到HyperMesh中,进行复杂几何体的处理再进行3D网格划分,通过quality index对划分好的网格进行质量评估,以inp格式文件导入Abaqus中进行边坡的稳定性分析计算,最后得到边坡失稳云图。地质模型导入有限元软件,实现了BIM技术与有限元技术的结合。这种技术流程提高了对地质情况的精确反映,插值计算后的模型曲面更真实地展现了地层的实际情况。一体化研究不仅使建筑、结构和岩土工程等多个领域的信息在一个统一模型中得以集成,而且有助于提高岩土工程分析精度和效率。

     

    Abstract: Establishing a three-dimensional geological model of the slope and performing stability analysis through the integration of BIM technology and finite element analysis software. A plug-in with spatial interpolation function is developed using Revit application program interface combined with Kriging interpolation method, and the plug-in is applied to the geological data to realize the refinement modeling of the geological model. The model is imported into HyperMesh through the geometry conversion interface to process the complex geometry and then mesh the 3D mesh, and the mesh is evaluated by quality index, and then imported into Abaqus in inp format to analyze the stability of slopes and calculate the slope instability cloud map. The import of geological models into finite element software enables the integration of BIM technology with finite element techniques. This technological process enhances the accurate representation of geological conditions, with interpolated model surfaces more realistically reflecting actual ground conditions. The integration study not only enables the integration of information from multiple fields such as architectural, structural and geotechnical engineering in a unified model, but also helps improve the accuracy and efficiency of geotechnical analysis.
