【摘要】：數(shù)值模擬是研究注漿過程的重要手段之一,但是數(shù)值模擬無法動態(tài)展示注漿全過程.為解決這一問題,本文對注漿全過程進(jìn)行三維動態(tài)可視化,從而使得"不可見"的注漿過程變得"可見",為注漿工程質(zhì)量管理提供強(qiáng)有力的技術(shù)支持.基于耦合FVM法的混合模型,本文對注漿全過程進(jìn)行了三維數(shù)值模擬,得到了注漿漿液時空分布規(guī)律;結(jié)合TIN算法、邊界表達(dá)技術(shù)和NURBS簡化技術(shù),建立了注漿區(qū)域內(nèi)的工程地質(zhì)三維統(tǒng)一模型;基于數(shù)值模擬成果和工程地質(zhì)三維統(tǒng)一模型,本文應(yīng)用網(wǎng)格曲面重建技術(shù)、虛實耦合技術(shù)、紋理映射技術(shù)對注漿全過程進(jìn)行三維動態(tài)可視化.工程實例研究表明三維可視化方法能真實、直觀地反映注漿過程中漿液的擴(kuò)散變化過程.
[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.
