摘　　要：混凝土坝施工进度常采用计算机仿真技术进行模拟,一般以大坝三维模型作为可视化表达载体,设计和施工仿真阶段模型颗粒度要求不同,模型数据和仿真结果交互不便,施工进度仿真可视化交互性不强。为实现不同阶段混凝土坝模型快速建模、模型属性和仿真数据关联应用、进度仿真可视化展示的高度集成和交互,提出了一种基于3DE的混凝土坝施工进度仿真动态可视化方法,并研发了混凝土坝模型快速分割、属性批量计算提取与数据交互、施工进度仿真动态展示等工具,最后以旭龙水电站混凝土拱坝为例进行实际应用并取得了良好的效果。结果表明:此方法具有操作简单、数据无损复用和可视化效果好的优势,可为混凝土坝施工仿真进度动态可视化研究提供新的思路。Computer simulation technology is often used to simulate the construction progress of concrete dams,in which,a 3D model of dams is generally used as the visual expression carrier.However,in this way the model granularity requirements are different during the design and construction simulation stages,the model data and simulation results are inconvenient to interact,and the visualization of construction progress simulation is not strong.In order to realize the rapid building of concrete dam model in different stages,the correlated application of model attributes and simulation data,and the high integration and interaction of progress simulation visualization display,a dynamic visualization method for concrete dam construction progress simulation based on 3DE was proposed,and tools such as rapid segmentation of concrete dam model,batch calculation and extraction of attributes and data interaction,and dynamic display of construction progress simulation were developed.Finally,the concrete arch dam of Xulong Hydropower Station was taken as an example for practical application.The results showed that this method has the advantages of simple operation,non-destructive multiplexing of data and good visualization effect,which can provide a new idea for the dynamic visualization of concrete dam construction simulation progress.
