摘　　要：通过有关计算,验证了某尾矿库各项设计措施的有效性。基于GEO-SLOPE数值模拟,对尾矿库在不同工况下的渗流和稳定性进行了综合评估。结果表明:在500年一遇的防洪标准下,该尾矿库东、西侧截洪沟的泄流能力和尾矿库库区溢洪道排泄能力均可满足要求。通过渗流计算分析,验证了尾矿坝的渗控措施的有效性,HDPE土工膜和排渗系统具有良好的防渗作用。在3种工况计算下,尾矿坝下游边坡的抗滑稳定性可满足设计标准。提出了布置人工观测和在线监测设施的建议,以实现对尾矿库坝体及排洪情况的实时监控。研究结果可以为尾矿库的设计、施工以及管理等提供技术参考。Through relevant calculation,the effectiveness of the design measures of a tailings pond was verified.Based on the GEO-SLOPE numerical simulation,the seepage and stability of the tailings pond under different working conditions were comprehensively evaluated.The results show that under the flood control standard of once in five hundred years,the discharge capacity of the flood interception ditch on east and west sides of the tailings pond and the discharge capacity of the spillway in the tailings pond area can meet the requirements.Through seepage calculation and analysis,the effectiveness of seepage control measures of tailings pond is verified.HDPE geomembrane and drainage system have good anti-seepage effect.Under the calculation of three working conditions,the anti-sliding stability of the downstream slope of the tailings pond can meet the design standards.The suggestion of arranging manual monitoring and on-line monitoring facilities is put forward to realize the real-time monitoring of dam of tailings pond and flood discharge situation.The research results can provide a technical reference for the design,construction and management of tailings pond.
