A slope is studied with limiting equilibrium method and finite element method comparatively. It is found that the results of the two methods are almost the same. The distribution of principal stress, maximal plastic strain, plastic zone, lateral displacement, vertical settlement and incremental of displacement can be investigated by FEM effectively, which make it easy to expediently choose the method of slope reinforcement and the position of strengthening.

The content of level has a big enough role in the value of the physical characteristic and the mechanical of material. The behavior of water in these materials needs to be analyzed first in order to support the slope stability analysis. Modeling of water behavior in materials in the construction of Tailing Storage Facilities (TSF) will be integrated in the slope stability analysis. This study aims to provide an explanation about the analysis of the Fishing Storage Facilities (TSF) which integrates transient groundwater analysis using the finite element method in supporting the stability analysis of the embankment of Tailing Storage Facilities (TSF). The variables that are used in the analysis, they are the parameters of physical properties and mechanic material for embankment and permeability parameters in analyzing groundwater. The analysis method for geotechnical and geohydrology modeling uses the finite element method. The results of analysis showed that groundwater behavior in the embankment material can be known in detail so that it can be integrated with stability analysis.   It can be seen that there is a decrease in the value of the slope safety factor using the Integrated Slope Stability Analysis method compared to the conventional method. Adding an impermeable layer using a thickness of 5 m of clay material and a thickness of 20-30 m to support the retaining wall/foot is the criterion of optimal stability. The required lining material thickness (D) can be expressed by the following drawdown percentage equation function:  reduction percentage = (1-0.8661D (-0.031)) * 100%.

Based on nonlinear finite element method, the character of embankment reinforced with geotextile on sloping weak foundation has been studied. It is shown that the lateral displacement of embankment has been distinctly effected by the sloping of foundation, the value of lateral displacement on sloping foundation is greatly bigger than that of horizontal foundation. The peak value of lateral displacement can be effectively reduced by geotextile. With the same condition, geotextile in sloping foundation acts a more important effect than that of horizontal foundation. The development of plastic zone of embankment has been impeded and separated by geotextile, which enhanced the stability of embankment. The results also indicated that, if necessary, reinforcement such as anti-slide pile should be layout at lower toe of embankment on sloping weak foundation.
