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%.

Element Method

Slope stability represents an area of geotechnical analysis in which finite element method provides a lot of benefits over limit equilibrium. In this paper, the authors apply a finite element code, PLAXIS, on slope stability analysis with various conditions to state out sensitivities of not only the soil parameters, slope configuration and groundwater condition but also numerical condition that one would encounter when making a FE slope design. It demonstrates that slightly conservative safety factor is obtained using FEM over the ones from limit equilibrium method. Intensity of mesh for simulation domain shall be selected as a fine level for an acceptable accuracy and economical computation time. Element nodes slightly affect the result of safety factor and final deformation of the slope.
