【摘要】：随着BIM技术在水利水电行业中的运用发展,创建仿真三维地质及枢纽建筑模型得到了大力推动,使得建立仿真整体枢纽有限元模型成为可能,进一步提升了数值模拟分析在工程建设及安全评价等工作中的作用。本文利用Rhino及Inventor软件建立心墙堆石坝枢纽区三维复杂地质模型及建筑物实体模型,结合Abaqus软件强大的实体布尔运算功能,避免了Inventor实体模型直接导入Abaqus时可能出现的几何信息错误,通过Abaqus对枢纽实体模型进行了有限元网格划分及优化,建立三维渗流有限元网格模型并进行了渗流特性分析。研究成果可为三维仿真建模及数值计算分析(CAD/CAE)集成技术提供参考。
[Abstract]:With the application and development of BIM technology in the water conservancy and hydropower industry, the establishment of 3D geological and hub building model has been greatly promoted, which makes it possible to establish the finite element model of the whole simulation hub. The function of numerical simulation analysis in engineering construction and safety evaluation is further enhanced. In this paper, the three-dimensional complex geological model and the building entity model of the core wall rockfill dam hub area are established by using Rhino and Inventor software. Combined with the powerful entity Boolean operation function of Abaqus software, the geometric information errors that may occur when the Inventor entity model is directly imported into Abaqus are avoided. The hinge entity model is meshed and optimized by Abaqus finite element method. The finite element mesh model of 3D seepage flow is established and the seepage characteristics are analyzed. The research results can be used as a reference for 3D simulation modeling and numerical analysis of CAD / CAE integration technology.
