| Abstract: | Combining the spatial analysis function of GIS with the limit equilibrium method,a visualization system(GiSlope) for soil slope stability analysis is developed.The visualizing establishment process of the analysis model is introduced.The setting of the analysis,slices division methods of random shape of slip surface and the method of confirming parameters are explained.Finally,several typical examples are put forward for comparing GiSlope with commercial software.The results prove that GiSlope is accurate and credible. |
