摘要
为进行尾矿库的防洪安全分析和稳定性分析,基于尾矿库调洪演算原理,对尾矿库等级、洪水量参数和防洪能力进行了定量分析。采用瑞典圆弧法对尾矿库进行稳定性计算,研究了在正常工况、洪水工况、特殊工况下的尾矿库安全系数变化,结果表明,尾矿库在不同工况下均处于稳定状态。
In order to analyze the flood control safety and stability of tailings reservoir,based on the principle of flood regulation calculation of tailings reservoir,the grade,flood volume parameters and flood control ability of tailings reservoir were quantitatively analyzed.The stability of tailings reservoir is analyzed by Swedish circle method.The safety factor changes of tailings reservoir under normal conditions,flood conditions and special conditions are studied.The results show that the tailings reservoir is stable under different conditions.
