中文摘要：

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。

英文摘要：

For the sake of researching effectiveness of the measures to improve the tailings pond stability, taking Fuxin Ahalai iron tailings pond as an example, physical simulation experiments were carried out. Change in saturation line was observed for an earth-rock dam and a permeable dam both as a starter dam. Difference in instability process was examined between two dams one of which was reinforced. The results show that： for all water levels, the permeable starter dam makes the saturation line obviously decrease, when the tailings pond is losing instability, first crack appears at the bottom of slope surface and develops to internal and upper of dam body, then on the top of the initial crack produces crack successively and expand, until the whole instability, when the reinforcement strip is setted, crack development spacing becomes small, the position of slip crack belt shallow, instability process slow and that tailings in slip crack belts slides through reinforcement strip and the speed is slower, the overall kinetic energy of the landslide is significantly decreased.
