Abstract_Chinese: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_English:Numerical simulation is one of the important methods to study the grouting process, but numerical simulation can’t show the whole process of grouting dynamically. To address this issue, a dynamic visualization method is adopted to make the invisible grouting process become visible, which provides strong technical support for the quality control of grouting engineering. Based on the coupled FVM method, the 3D numerical simulation of the whole grouting process is carried out, and the temporal and spatial distribution law of grouting slurry is obtained. Combined with TIN algorithm, boundary expression technique and NURBS simplification technique, a 3D unified model of engineering geology in the grouting area is established. In this paper, 3D dynamic visualization of the grouting process is carried out by using mesh surface reconstruction technique, virtual reality coupling technique and texture mapping technology coupled numerical simulation results and 3D unified model of engineering geology. The case study demonstrates that 3D visualization could be an effective tool for presenting the dynamic changes of grouting slurry diffusion process visually and realistically.
