摘　　要：加高扩容后尾矿坝的抗滑稳定性,是决定尾矿库能否加高扩容的关键因素,而如何建立计算模型、选择计算参数,如何根据稳定性计算结果确定设计方案,是广大设计者关心的重要问题。本文通过对某尾矿库加高扩容的稳定性分析,简述了加高扩容过程中稳定性分析原则,分析探讨了计算模型的建立、参数的选择、治理方案的确定等问题。The stability of tailings dam after high expansion is the key factor to decide whether the tailings reservoir can be expanded or not.How to establish the calculation model,select the calculation parameters and determine the design plan according to the stability calculation results is an important issue for the designers.Based on the stability analysis of a tailings reservoir heightening expansion,this paper briefly introduces the principles of stability analysis in the process of heightening and enlarging capacity,and analyzes and discusses the establishment of calculation models,the selection of parameters and the determination of treatment plans,etc.,for the designers to analyze and discuss.
