为分析筋带在尾矿坝漫坝破坏过程中的阻滞性,基于相似理论和溃决侵蚀原理,进行加筋尾矿坝漫顶破坏模型试验。深入剖析加筋尾矿堆积坝漫顶演化规律和破坏模式,揭示筋带在尾矿坝漫顶破坏过程中的阻滞效应。结果表明:加筋尾矿坝的浸润线上升滞后于未加筋情况;加筋尾矿坝漫坝破坏呈台阶破坏模式;筋带对尾矿坝漫坝破坏发展速度和侵蚀沟深宽有明显的阻滞作用。采取尾矿坝加筋措施能有效防御洪水漫顶溃坝灾害。
In order to analyze the retardation of tendons in the dam overtopping process of tailings dam, based on the similar theory and the theory of collapse erosion, the model test of the tailings dam under overburden destruction was carried out. In-depth analysis of the evolution and failure modes of the reinforced tailings dam, and reveals the blocking effect of the tendons in the process of tailing dam overhanging. The results show that the infiltration line of the tailings dam lags behind that of the unstirred condition. The dam failure of the reinforced tailings dam shows a step failure mode. The effect of the tendons on the speed of dam damaging and the width of the erosion ditch is obvious Blocking effect. Tailings dam reinforcement measures can effectively prevent flooding flood collapse disaster.
