| Abstract: | The nonlinear monitoring curve of ground movement resulted from mining process is fitted by means of the fractal interpolation method, the state evolution on ground movement time series is analyzed by use of R/S (Rescaled Ranged Analysis) fractal time series, the development of the damaged fracture is simulated and predicted. The results show that for the adoption of fractal theory to the nonlinear data analysis of ground movement, the nonlinear characteristic of ground movement is realistically described, especially, the calculation is simplified. |
