Transportation construction in the western region, the construction and development of mountain highway very rapidly, due to the complex geological environment mountain, high fill roadbed therefore appear more and more. High stability Embankment largely determines the quality of the road. In practical engineering, construction accident caused by slope instability due uncommon. Therefore, an important part of the project is to study the stability of the slope. By using Lizheng geotechnical software and finite element software and other methods for some road high fill slope stability analysis. Finite difference method, limit equilibrium method and finite element method is the primary method for slope stability analysis of high fill path analysis. Therefore, this article also compares these methods, and draw their own advantages and disadvantages of these methods, and these methods were evaluated. Slope stability analysis is to find a safe and reliable form of slope and slope stability values.
