摘　　要：采用工程类比法,提出了将预测边坡失稳的灰色-突变理论应用于尾矿库坝体稳定性分析及失稳时间预报中。以某尾矿库2号坝体的水平位移监测数据为例,对该坝体的稳定性和失稳时间进行了分析预测,通过预测结果与工程实际情况的对比,表明该方法在尾矿坝的失稳预测中具有一定的适用性和合理性。By using engineering analogy method,the grey-catastrophe theory that used in forecasting slope failure was presented to predictstability and failure time of tailing dam.Taking the horizontal displacement monitored from No.2dam in one tailing dams as an example,the stability and failure time were analyzed and predicted.Through comparing the predicted results with engineering actual situation,the grey-catastrophe theory was proved to be a reasonable and suitable method in instability prediction of tailing dams.
