库岸滑坡地质灾害三维演变动态显示方法
Method of Dynamic Evolution Process Display for Reservoir Landslide Geological Disaster in 3D Scene
摘要
Abstract
Taking one typical huge landslide in Nuozhadu hydropower station in Lantsang as example, on the basis of data analysis and practical operations, dynamic and integrated display methodology for the process of landslide sliding, water swelling when the slide falls into water and the waves spreading in 3D scene by IDL programming language was developed and completed. This approach integrated the ability of massive data calculation and visualization. First, the operation of extraction and separation for the data updated were completed, which would reduce the difficulties in updating the data. Second, the 3D scene was divided into three models: terrain, landslide and river. And each model would be controlled much better. Last but not least, integrating the process of landslide sliding, water swelling when the slide falls into water and the waves spreading into a dynamic entirety was realized, and the evolution process of landslides was redisplayed. The results show that each model of the whole dynamic evolution process connects well, and the data operation for each model is simple and controllability is good. So, all above proves that the method developed in this paper is effective for dynamic evolution process display for reservoir landslide geological disaster in 3D scene.关键词
