To solve the problem of safety and stability of the uranium tailings impoundment dam, based on the whole process of emergency management, the safety and stability evaluation system of the uranium tailings impoundment dam is established by using analytic hierarchy process (AHP) from the four aspects of design and construction, natural environment, operational stability and management, and the general weight of each evaluation index is calculated; the improved AHP-cloud model is introduced to obtain the basic evaluation cloud map for the safety and stability of the uranium tailing dam and two typical dams were evaluated in a large uranium tailings impoundment in southern China. The results show that the model can produce a more accurate evaluation of the safety and stability of the uranium tailings impoundment dam, and provide a reference for the subsequent decommissioning management work.

铀尾矿库坝安全稳定性评价——基于改进的AHP-云模型

针对铀尾矿库大坝安全稳定问题，基于应急管理全流程，运用层次分析法（AHP）从四个方面建立了铀尾矿库大坝安全稳定评价体系设计与施工、自然环境、运行稳定性与管理等方面的评价，并计算各评价指标的总权重；引入改进的层次分析法云模型，得到铀尾矿坝安全稳定性的基本评价云图，并对我国南方某大型铀尾矿库的两座典型坝进行了评价。结果表明，该模型能够对铀尾矿库坝的安全稳定性进行较为准确的评价，为后续的退役管理工作提供参考。
