Slope stability is one of the important analysis not only human being and economic issues but also environmental and sustainability aspects as well. There are analysis softwares available to search factors of safety calculations as well as stabilization methods. Slide is one of the most comprehensive slope stability analysis software available, complete with finite element groundwater seepage analysis, rapid drawdown, sensitivity and probabilistic analysis, and support design. All types of soil and rock slopes, embankments, earth dams, and retaining walls can be analysed. In this study, effects of groundwater level is investigated in terms of stability analysis of embankments and earth fill barriers. Embankments and earth fill barriers are constructed on soft clay soil materials. Different scenarios and input parameters are used in the analysis. Embankment and earth fill barriers slope, shape and geometries are taken from according to Directorate General of Road Transport Regulation. Factors of safety are very variable due to changing groundwater locations.
