| 摘 要： | 早期建设的尾矿坝大多已达到或接近最初设计高度而需要加高扩容,加高扩容后尾矿坝的渗流稳定是人们最为关心的问题。重点分析了尾矿坝与普通土坝的不同地震反应特征,采用简化的常量动态分布系数确定尾矿坝坝体的地震惯性力。详细给出了震区的一座拟加高扩容尾矿坝的渗流与稳定分析,并对该尾矿坝的加高扩容提出了建议。 |
| 关 键 词： | 尾矿坝 加高扩容 渗流 地震 稳定性 |

| Abstract: | Most of tailing dams built in early years need to be heightened for expand the storage because their heights have reached or are near to their initial ones.The seepage stability of heightened dam is the major issue concerned.The different earthquake response between tailing dam and common earth-filled dam is analyzed,and simplified constant dynamic distribution coefficient is employed to confirm earthquake inertia force of tailing dam body.The seepage and stability of a tailing dam to be heightened in earthquake region are analyzed in detail and some suggestions are also put forward accordingly. |
| Keywords: | tailing dam heightening seepage earthquake stability |
