基于约束TIN的开采沉陷可视化及预计

本文以开采沉陷损害和传统预计方法为背景,以优化预计方法和提高预计精度为目的,对开采沉陷的三维可视化表达进行了研究,通过一个实例分析了开采沉陷对地面建筑物的影响及可视化的预计过程。在可视化模型的建立过程中,根据岩层和地表移动的特点对Delaunay三角剖分算法做了进一步改进,通过内插特征点模拟变形等值线,使岩层的细节变化更为直观,该方法对于开采沉陷的三维可视化及变形的预计具有积极的意义。

Visualization and Intending of the Exploitation and Subsidence Based on Constraint TIN

According to the exploitation and subsidence and the traditional estimating mean, this paper investigates three-dimension visualiza- tion of the exploitation and subsidence in order to optimize the estimating mean and enhance the estimating precision, moreover via an exam- ple, it analysis the impact of buildings on the ground and the intending process of visualization. In the process of establishing the visual mod- el ,this dissertation improves on lhe arithmetic based on floating characteristics of terrane and the surface, and use interpolation characteristic points to simulate the distortion isoline. The specific changes are more intuitionistic. This method is actively significant to visual three -dimension and the inteoding of the distortion.
