When a road embankment is built, the safety factor is analyzed as one of the most important variables in the design; since it is necessary that slopes are safe and stable. In most cases, a static analysis is used for design purposes. This paper presents results of a study on the seismic behavior of the safety factor of slopes, in high road embankments under seismic action. An experimental design 32 was performed for this study. In the experimental design, three different embankment heights were considered and the level of seismicity was varied through accelerograms from the design spectrum bearing in mind the parameter of the section 3.1 of the “Manual de diseno de obras civiles de la comision federal de electricidad” of Mexico. To obtain the results, the finite element method (FEM) and the Newmark method were employed by the software Geo-Studio; using the sub-modulus QUAKE/W for dynamic analysis, and the sub-modulus SLOPE/W for stability analysis. The results shown the necessity to review these structures in high intensity seismic regions for embankments higher than 12 m.
