摘要
以金沙江两家人滑石板高边坡为例,通过由AutoLisp语言编程提取的AutoCAD地形图元,给出了栅格网格地形和任意网格地形的可视化模型,并利用该模型分析了滑石板高边坡演化过程,同时根据该模型中的滑塌岩体体积及未滑塌地形特征还原了滑塌边坡原地形.仿真结果表明,三维AutoCAD可视化模型可为滑石板边坡的数值分析提供地质和力学模型,在水利水电工程的边坡工程中可取得较好的应用效果.
The Huashiban slope on Jinsha River was taken as a case. The AutoCAD graphic elements of the topography were extracted by programs with language AutoLisp. The grid topography and arbitrary topography were both introduced to establish a 3D visualization model. Based on the visualization model, the evolution process of Huashiban slope was analyzed, and the original topography was simulated according to the amount of landslide rock and the characteristics of residue topography. The simulated results show that the 3D visualization topographic model can be employed to establish geological and mechanical models for numerical analysis, and it is applicable to the high slopes in hydraulic and hydropower engineering.
