摘　　要：为了研究沉积特性对尾矿库坝体稳定性的影响,基于尾矿沉积不均匀特性的重要性,采用Slide软件对云南某尾矿库建立坝体的稳定性模型,来分析计算尾矿坝在正常、洪水、特殊工况下稳定性的可靠度及尾矿材料的敏感度。结果表明:尾矿库在正常、洪水运行条件下的可靠性指标符合规定,但是在特殊运行条件下的可靠性指标低于规范值,不满足安全生产要求。3种运行条件下,尾细砂对尾矿坝的稳定性影响最大。In this paper,we have made our studies in the influence of sedimentary characteristics of the tailings dam stability on base of the importance of tailings deposition uneven characteristic.We use the slide software as a tailings dam in stability model,which is established to analyze the calculation of tailing dam under normal, including flood,special working condition of three kinds of the sensitivity of the reliability and stability of the tailing material.The results show that the tailings in the normal,flood operation under the condition of reliability index will conform to the rules.In special operating conditions,the reliability index is lower than the standard value.It will not meet the requirements of safety in production.In three kinds of operation conditions,tail sand influence on the stability of tailings dam is the largest.
