摘要: 采用Geostudio软件,运用Bishop法对某正在营运的尾矿库渗流情况及稳定性进行了分析,明确了加高前后尾矿坝的浸润线位置、不同位置饱和度、水平向位移及其渗流规律,得出了不同工况下尾矿坝的稳定性系数,分析了加高前后尾矿坝的稳定性,表明该尾矿坝目前阶段稳定性较好。

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
