Three-Dimensional Dynamic Visual Simulation of Slope Instability of Barrier Landslide

Abstract:

The sliding movement of barrier landslide is a complex and dynamic process, because of the great effect of seismic action and huge surge. Adopting NURBS-TIN-BRep hybrid data structure and integrating with multi-source geological data, 3D geological model of the Tangjiashan quake dam was rebuild. The instability mechanism of the landslide was analyzed. Applying visualization technology, the whole formation process of the barrier dam, the production and development process of surge were fully and realistically displayed. These results above can help the engineering personnel to understand the whole condition of the Tangjiashan barrier dam. These research can provide some technical support for comprehensive governance scheme.
