摘　　要：为预测尾矿坝竖向位移,在分形理论的基础上,利用常维分形和变维分形两种方法,对尾矿坝竖向位移的监测数据进行分析和预测,得出结论:对于不能直接利用常维分形方法分析的数据,可以利用变维分形的方法对数据进行N阶累计和处理后,使得各段分维形数非常接近,利用前面已知的分维形数预测下一段的分形维数,再计算出后面竖向位移,所得预测数据与实际监测数据相对误差较小.Based on fractal theory,using the constant dimension fractal and the variable dimension fractal methods,this study analyzed and predicted the vertical displacement monitoring data of tailings dam.The analysis result indicates that those data were analyzed and forecasted by the general constant dimension fractals by using this method in which a set of transforms were taken as various orders of the accumulative sum of N,which couldn't be analyzed by constant dimension fractal.If fractal dimension of each section was very close,fractal dimension of the next section was predicted with previous fractal dimension and then calculated vertical displacement.Relative errors were small between forecast data and actual monitoring data.
