【摘要】：数值模拟是研究注浆过程的重要手段之一,但是数值模拟无法动态展示注浆全过程.为解决这一问题,本文对注浆全过程进行三维动态可视化,从而使得"不可见"的注浆过程变得"可见",为注浆工程质量管理提供强有力的技术支持.基于耦合FVM法的混合模型,本文对注浆全过程进行了三维数值模拟,得到了注浆浆液时空分布规律;结合TIN算法、边界表达技术和NURBS简化技术,建立了注浆区域内的工程地质三维统一模型;基于数值模拟成果和工程地质三维统一模型,本文应用网格曲面重建技术、虚实耦合技术、纹理映射技术对注浆全过程进行三维动态可视化.工程实例研究表明三维可视化方法能真实、直观地反映注浆过程中浆液的扩散变化过程.
[Abstract]:Numerical simulation is one of the important methods to study grouting process, but numerical simulation can not show the whole grouting process dynamically. In order to solve this problem, the 3D dynamic visualization of the whole grouting process is carried out in this paper, which makes the "invisible" grouting process "visible" and provides strong technical support for the quality management of grouting engineering. Based on the hybrid model of coupled FVM method, the 3D numerical simulation of the whole grouting process is carried out, and the temporal and spatial distribution of grouting fluid is obtained, which combines tin algorithm, boundary representation technique and Nurbs simplification technique. Based on the results of numerical simulation and the 3D unified model of engineering geology, the mesh surface reconstruction technology and virtual reality coupling technology are used in this paper. Texture mapping technique is used to visualize the whole process of grouting. The research of engineering example shows that the 3D visualization method can reflect the diffusion process of slurry in grouting process.
