摘　　要：尾矿坝坝体位移是影响尾矿坝稳定的一个重要因素,为了研究坝体位移的发展趋势,根据某尾矿坝坝体竖向位移的监测数据,利用R/S分析法分析其位移发展趋势,进而揭示该发展趋势对尾矿坝稳定性的影响。结果表明：该尾矿坝各监测点的Hurst指数值介于0.82~0.93之间,均大于1/2,且第4和第5监测点的Hurst指数值达到0.9以上,说明该尾矿坝坝体竖向位移有增强趋势,尤其第4、第5监测点增强趋势最明显,是重点监测的部位;通过研究可以看出R/S分析法在尾矿坝监测预警中具有较好的应用价值。The dam displacement is an important factor affecting stability of tailings dam.In order to study dam displacement trends,the displacement monitoring data were collected and the displacement tendency was analyzed through R/S analysis method.In this case,the influence of displacement trends on stability of tailings dam was revealed.The results showed that Hurst indexes of monitoring points in tailings dam were arranged between 0.82 and 0.93.All of the Hurst indexes were over 0.5,on the 4th and the 5th monitoring points,the Hurst indexes were more than 0.9.It showed that vertical displacement of tailings dam had strongly developed,and the 4th point and the 5th point were key locations for monitoring.It can be seen that R/S analysis method has application value in tailings dam monitoring and pre-alarming.
