∗ 2022 年度四川省住房城乡建设领域科技创新课题：基于数字孪生技术的 NURBS 曲面体钢网壳智能建造研究（SCJSKJ2022-34）

摘要：

金沙演艺综合体项目城市雨棚为大跨度 NURBS 曲面体单层相贯圆管钢结构网壳。提出一种融合数字孪生技术的 NURBS 曲面体网壳拼装提升施工技术，将数字孪生技术等智慧建造理念融入其中，实现数字化施工指导。在数字孪生层面，采用 Revit,Tekla 软件进行三维建模，并利用 MIDAS Gen,3D3S 等软件进行验证计算；在物理孪生层面，基于三维扫描重建技术和 BIM-QR 技术，对构件加工、拼装进行复核验证。最终采用渐扩渐升方法进行NURBS 曲面体网壳不等高分步累积整体提升。基于数字孪生五维模型，确保 NURBS 曲面体单层相贯圆管钢结构网壳的安装效果，从而满足结构安全与建筑造型要求。

The urban canopy of Jinsha Performing Arts Complex project is a large-span NURBS curvedreticulated single-layer intersecting tubular steel reticulated shell. A NURBS curved reticulated shellassembly and lifting construction technology integrating digital twin technology is proposed,whichintegrates the intelligent construction concepts such as digital twin technology into it to realize digitalconstruction guidance. At the digital twin level, Revit and Tekla software were used for three-dimensionalmodeling, and MIDAS Gen and 3D3S software were used for verification and calculation. At the physicaltwin level, based on the three-dimensional scanning reconstruction technology and BIM-QR technology,the component processing and assembly are reviewed and verified. Finally, the method of gradualexpansion and gradual rise is used to carry out the step-by-step cumulative overall lifting of the unequalheight of the NURBS curved reticulated shell. Based on the digital twin five-dimensional model, theinstallation effect of the NURBS curved single-layer intersecting tubular steel reticulated shell is ensuredto meet the requirements of structural safety and architectural modeling.
