摘要
基于可视化仿真技术的大型水利水电工程中大体积混凝土裂缝的机理模拟与展示方法研究越来越受关注.分析了国内外对裂缝三维建模方法的研究;基于大体积混凝土裂缝统计数据,利用NURBS软件平台,对具有复杂大坝条件和廊道群的水利工程坝体结构裂缝建立了三维模型拓扑关系.以实现坝体结构裂缝虚拟现实系统为目标,完成了大坝裂缝控制模拟、可视化查询和综合分析等方面的应用.最后将该技术成功应用到实际水利工程的三维坝体结构裂缝统计模拟和可视化分析中,为裂缝虚拟现实可视化方法在其他工程领域的应用拓展提供参考.
The research on the mechanism simulation and display of mass concrete crack based on the visual simulation technology in large-scale water conservancy and hydropower engineering has gotten more and more attention.In this paper,the researches about three-dimensional modeling method of cracks at home and abroad are analyzed.Then,based on the statistical data of mass concrete cracks,using NURBS software platform,the topological relation of three-dimensional crack model for water conservancy and hydropower engineering with complicated dam conditions and gallery groups is established.In order to realize the dam structure cracks in virtual reality system for a target,the application of the simulation of dam crack control,visual query and comprehensive analysis and so on are finished.Finally,the three-dimensional model and visual analysis are applied to simulating crack structure in the actual water conservancy engineering.This can provide a reference for the application of three-dimensional crack visualization based on virtual reality in other engineering fields.
