本文认为提高尾矿坝的安全度,目前采用降低坝体浸润线的方法,仍是确保坝体安全的重要途径。采用无人管理排渗方式——无渗砂混凝土管应用于尾矿坝进行了大量的试验研究,表明在歪头山铁矿尾矿坝沿轴线方向埋设无渗砂混凝土管的排渗措施,达到了降低浸润线的目的,效果良好。 This paper argues that to improve the safety of tailing dam, the method of reducing the saturation line of dam is still an important way to ensure the safety of dam. Adopting the unmanned drainage method - no sand-permeable concrete pipe applied to the tailings dam for a large number of experimental studies show that in the Waituanshan iron ore tailings dam buried along the axis direction of the seepage-free sand concrete pipe drainage measures, Achieved the purpose of reducing the infiltration line, the effect is good.
