为探究提高尾矿库稳定性措施的有效性,以阜新阿哈来铁尾矿库为例开展物理模拟研究,分别对比初期坝为土石坝和透水坝时尾矿库浸润线的变化,加设筋带与未加设筋带坝体的失稳过程差异。结果表明,各种库水位条件下,透水初期坝使尾矿库浸润线显著降低,尾矿库失稳时,首先在底部坡面出现裂纹并向内部和上部发展,之后在初始裂纹上部依次产生裂纹并扩展,直至整体失稳,加设筋带时裂纹发展间距小,滑裂带位置浅,失稳过程缓慢,滑裂带尾矿滑经筋带时速度减慢并滚动,滑坡体的整体动能显著减小。
In order to explore the effectiveness of measures to improve the stability of tailings ponds, a physical simulation study was carried out in Fuxin Ahalaite tailings mine. The change of wetting line of tailings ponds at the time of initial dam being earth-rock dam and permeable dam was compared respectively. The difference of instability process between tendons and unbonded bars. The results show that under various water level conditions, the infiltration dam of tailings reservoir significantly reduces in the initial period of water permeability. When the tailings reservoir is unstable, the cracks first appear on the bottom slope and develop toward the interior and the upper part, and then occur in the upper part of the initial crack Cracks and spread until the overall instability, the increase in the time of the crack with the reinforcement zone spacing, slippery zone shallow, slow instability process, the slippery tailings slip through the tendons slow down and roll, the whole body of the landslide Kinetic energy is significantly reduced.
