尾矿坝稳定性精细化评价方法的研究

摘要

尾矿库安全与否关系到下游居民生命财产与矿山生产的安全，必须确保其安全运行，因此，需要实时了解和掌握尾矿坝生产期间稳定性的动态演变特性及其安全性。针对现有评价方法的不足，借鉴边坡稳定性评价中精细化评价理论，结合尾矿坝体、基底及其筑坝特点，建立了尾矿坝精细化评价方法。并结合具体工程实例将新方法的评价结果与传统分析结果进行了对比与分析，结果表明，精细化评价方法的评价结果具有更高的可靠性与精度高的特点，更加接近稳定状态的真值，从而为尾矿坝的安全评价与设计提供了决策依据。%The safety status of tailings is related to the lives and properties of downstream residents and the work safety of mine, and its safe operation is imperative.Therefore, the dynamic evolution characteristics and safety a-bout stability of tailings dam during the production should be grasped and known in real-time.In this paper, aiming at the shortcomings of the existing evaluation methods, based on detailed evaluation theory in slope stability evalua-tion, combining with the characteristics of tailings dam, basal and dam construction, a detailed evaluation method of tailing dam was established.Combing with special engineering project, the evaluation results were compared and analyzed with that of traditional method.It showed that the result of detailed evaluation method has the characteris-tics of higher reliability and high precision, which is closer to the true value in stable state.It provides a decision-making basis for safety evaluation and design of tailings dam .
