基于ORD的面板堆石坝建模关键技术与应用

Key Technology and Application of Concrete Face Rockfill Dam Modeling Based on ORD

针对面板堆石坝在大坝前期设计阶段方案比选多、工作量大的问题,结合面板堆石坝结构设计原理,提出一种基于ORD软件的参数化建模方法,即利用OpenRoads Designer软件研究创建面板堆石坝BIM模型的关键环节和要点,并实现将坝体结构转换为一系列逻辑约束的组件来创建坝参数化模板,并将其应用于贵州省望谟县某面板堆石坝方案比选中。实际应用结果表明,该方法用于面板堆石坝建模和前期设计方案比选切实可行,大大提高了设计效率,且成果输出展示更直观,为面板堆石坝BIM技术应用提供了新思路。

Aiming at the problem of large workload and multiple scheme selection in the early design stage of the face rockfill dam,combined with the principle of the structure design of the face rockfill dam,a parametric modeling method based on ORD software was proposed,that is,the key links and key points of the BIM model of the face rockfill dam were created by OpenRoads Designer software,and the dam structure was converted into a series of logical constraint components to create the parametric template of the dam.The method was applied to the scheme selection of a face rockfill dam in Wangmo County,Guizhou Province.The practical application results show that the method is feasible for the modeling and early design scheme selection of the face rockfill dam,which greatly improves the design efficiency and the output of the results is more intuitive,providing a new idea for the application of the BIM technology in the face rockfill dam.
