| 摘 要： | 介绍了一种滑坡区域的真三维数字模型仿真方法.通过已知的滑坡区地形数据,结合地质工作人员提供的剖面图,可以重建该区域的地下不同岩层属性及滑动面等与地质灾害紧密相关的地质结构.模型采用了基于三棱柱体体元的建模方法.实验结果证明该方法能较好地解决基于层状地质结构的三维仿真,能有效地将采样所获得的各种空间数据相融合,实现滑坡区域的真三维模拟,为地质灾害区域的防治提供可视化手段.

| Abstract: | This paper introduces a method on real 3D modeling of landslide which is based on the integration of all kinds of space data such as aerial photos, GPS, DEM, boreholes, section images etc. Tri-prism elements are used to construct the multilayer geologic structure of landslide area. The application of the modeling is presented and the result shows that this method can deal with complex geologic structure of landslides. The real 3D modeling of landslide provides a visual measure and has great application potential in the monitoring and prevention of geological hazards. |
