Three-Dimensional Slope Stability Analysis Methods Based on GIS Technology

Abstract:

By using imbalance thrust force method, the slope stability factor based on three-dimensional slide block was deduced. According to the borehole data of highway, the TIN data layer and grid data layer for three-dimensional slope stability analysis were carried out by use of ArcMap. The value of each gird cell of different layers are picked up as slide block, it makes convenience in the slope stability analysis. Considering the property of bedding landslide, the three-dimensional slope stability analysis program based on VBA of ArcGIS is put forward in this paper. Taking one of the large rocky landslides as an example, the results of the three-dimensional stability analysis with slope before and after excavation, as well as the different water level conditions are compared. Furthermore, the directive significance of the three-dimensional method in landslide harness engineering was discussed.
