With slope project of a large open-pit mine as background, slope stability calculation models of MSARMA are built based on the modified limit equilibrium theory, to calculate the slope stability coefficient and analyze the slope sensitivity analysis under different factors. Relying on GIS platform and three-dimensional visualization technology, the three-dimensional visualization geological models of open-pit mine slope are built. Then, the stability coefficient is imported into GIS platform, and the spatial interpolation, data overlaying technologies are adopted to get three-dimensional visualization zoning of the slope. With the application of methods above and informational ways, the stability calculation data, dynamic curves, and three-dimen- sional visualization zoning images of the slope are achieved, so as to present the open-pit mine slope stability condition through multi angles and multi dimensional ways.
