3-D Dynamic Simulation and Visualization of Landslide Models - A Case Study of the Shum Wan Road Landslide in Hong Kong

摘要

This paper builds a group of landside-related models including the model of geometric and physical parameters of landslide, sliding direction and stability coefficient model, specific stability coefficient model based on dynamic geographical environments, and dynamic process model of landslide. The dynamic relationship between landslide's stability coefficient and landslide band soil's water content, and internal cohesive force under varied space-time distribution are studied. A landslide simulation and visualization system is designed and developed for model computation and 3-D visualization of landslide process. The system and landslide-related models are used for studying the Shum Wan Road landslide in Hong Kong.
