摘　　要：为了揭示尾矿坝浸润线埋深对于整个坝体稳定性的影响,以甘肃某尾矿坝为工程研究对象,建立三维有限元模型,研究不同标高时坝体的渗流稳定性。研究结果表明:不同工况下浸润线分布规律基本相同,考虑排渗设施作用下,各标高时无坡面溢出现象,均满足规范对浸润线最小埋深的要求。根据三维渗流模拟计算结果 ,不同标高工况下尾矿坝不会有渗透变形或渗透破坏等情况的发生,尾矿坝坝体渗流稳定性满足要求,但在之后的堆积过程中应继续加强浸润线的监控和控制。In order to reveal the influence of the saturation line depth of tailings dam on the stability of the whole dam body,a three-dimensional finite element model is established to study the seepage stability of the dam body at different elevations by taking a tailings dam in Gansu Province as the engineering research object.The results show that the distribution law of saturation line is basically the same under different working conditions.Considering the effect of drainage facilities,there is no slope overflow phenomenon at each elevation,which meets the requirements of the specification for the minimum buried depth of saturation line.According to the results of three-dimensional seepage simulation calculation,there will be no seepage deformation or seepage failure in tailings dam under different elevation conditions.The seepage stability of tailings dam meets the requirements,but the monitoring and control of saturation line should be strengthened in the subsequent accumulation process.
