Abstract
 A GIS System Development for Evaluating 3D Slope Stability Track: Mining and Geosciences Author(s): Cheng Qiu, Tetsuro Esaki, Mo Xie, Yasuhiro Mitani, Chun Wang When using a 3D deterministic model to evaluate the landslide susceptibility of regional area, processing large amounts of spatial data and identifying the objective for applying the deterministic model would be arduous works. In this research, an enhanced hydrology tool is developed to automatically identify the objectives of research, which are called slope units, from terrain raster data. A new grid-based 3D slope stability model is applied to evaluate the failure probability. Finally, the landslide susceptibility map showing the location and the shape of potential slope-failures is obtained. All the approaches are implemented by an integrated system which has been developed in ArcGIS 9.0 using ArcObjects. This system convert all related input data, including topographic and geological raster data, to a point dataset for calculation. The output will be a polygon shapefile of the critical slip surfaces with the attributes of failure probability and the minimum safety factor.
