Three-dimensional Seepage Stability Analysis of a Large Valley Tailings Reservoir
The position of saturation line in the dam is one of the important factors for the safety and stability of tailings reservoir.Taking a large valley tailings reservoir as the background,the three-dimension-al seepage numerical model of the tailings reservoir is established by using the seepage analysis in the finite element analysis software MIDAS/GTSNX.The three-dimensional seepage field simulation analysis of the tailings reservoir dam body is carried out,and the influence of seepage discharge measures on the seepage field is considered respectively.The distribution law of saturation line position and hydraulic gradient under normal and flood operating conditions is obtained by simulation.The location of the saturation line in the tail-ings reservoir dam is significantly affected by the drainage facilities,and the reasonable setting of the drain-age facilities is conducive to the seepage stability of the tailings reservoir.
