Sanitary landfills are of great importance for the maintenance of cities, because they send their solid waste to final disposal correctly, once landfills are designed to protect the environment against the effluents of these wastes and, due to the risk to the environment, their geotechnical and environmental monitoring are essentials. The project is about the three-dimensional modeling and stability analysis of a large landfill through computational tools in order to verify the feasibility of using the software Rocscience Slide3 - 3D Limit Equilibrium Analysis for Slopes. The three-dimensional modeling of the landfill is based on the topographic survey and the use of Autodesk AutoCAD Civil 3D software to refine the data, enabling manipulation in Slide3. In this work are considered two methods of slope stability analysis - Bishop Simplified and Morgenstern-Price - aiming to compare their results in relation to the landfill behavior when arbitrary geotechnical parameters are assigned on the variation of the coefficient in the massif. The landfill stability analyzes were focused on the east side in order to cover three different slopes - north, east and south - allowing the observation of comparisons of behavior in different areas against the same coefficient
