Abstract The spillway excavating slope is belonging to artificial excavating slope，which is different from general natural slope and has the characteristics of the high mountain and steep slope within the construction area. The spillway excavating slope stability is usually analyzed with limit equilibrium theory. However，as the established 3D geological model is not precise enough，the auto subdivision process visualization is not existing，and the computing interface of the stability analysis is not friendly enough，it is difficult to unify the vivacity and the clarity. In this paper，a 3D geological model of the studied region was built up，and the NURBS technology was used. The second development of the 3D geological software VisualGeo was carried out. It realized the auto subdivision of the 3D slope and the data extraction. While the improved 3D visual simulation and analysis system VisualSlope was used to calculate the stability，to analyze the sensitivity of the parameters and to research the support measures. This method realized the visual analysis and the directly demonstration of the slope stability，developing a new way for the slope stability based on 3D geological model and research of visualization analysis.

Key words： slope engineering visualization auto subdivision 3D geological model
