Abstract: Three dimensional slope stability analysis is a very complex issue. Setting research on the stability of a wedge on the large spillway slope as an engineering example,based on GIS,we approached to the use of three-dimensional slope stability limit equilibrium analysis. After data ac-quisition,spatial processing,modeling and safety factor calculation,we not only drew the safety factor of the slope,but also showed the distribution of the sliding forces and their direction on the critical sliding surface. And then,in accordance with the spatial relationship between weak layers and anchors,we proceeded the anchor support adjustment programs.
