摘要: 根据尾矿库的具体工程地质条件,采用渗流分析软件对尾矿库进行渗流数值模拟计算。考虑尾矿库渗透水在尾矿堆积体内流动时做低雷诺数的层流运动,以线性达西定律为基础,模拟不同坝高在正常运行工况和洪水运行工况下的渗流数值计算。结果表明:在冲沟的位置有较大的速度矢量,对流沙的裹挟会使局部危害加剧;库内水位向下游尾矿堆积坝体的渗透过程中,总水头最大,浸润线在坝顶部逸出可能性最大,最容易发生渗流破坏。

Abstract: According to the specific engineering geological condition of tailings reservoir, simulation calculation of seepage numerical were done on tailings reservoir by seepage analysis software.Considering seepage water of tailings reservoir does flow movement of low Reynolds number during flowing in tailings deposit body, seepage numerical calculation of different dam heights under normal and flood running condition were simulated based on linear Darcy law.The results show that velocity vector is much big at gulch position, quicksand carrying could intensify local hazards; total head was biggest around waterside and the possibility of saturation line overflowed at top of dam was biggest during the infiltrating process of reservoir water level to downstream tailings accumulative dam, and seepage destruction was mostly liable to happen.
