Abstract: Tailings dam is the structure constructed with refuse.The heterogeneous nature of the construction material,complexity of construction history,and the coupled interaction between stress field and seepage field makes the seepage and stability analysis difficult.GeoStudio software was used to analyze the seepage condition of a tailing dam in operation.Seepage analysis was performed to obtain the phreatic surface before and after the proposed construction to increase the height of the tailing dam, along with the degree of saturation,and flux.The information obtained from seepage analysis was then used in slope stability analysis to assess the factor of safety for proposed construction.

Key words: Tailing Dams, Seepage Analysis, Side Slope Stability Analysis
