Deformation prediction and safety analysis of Xiaodejiang landslide in Nanning-Kunming Railway

Based on the analysis of the geological condition and deformation of Xiaodejiang landslide, the deformation tendency of Xiaodejiang landslide before anti-slide pile constructed is predicated according to the long-term monitoring data. The analysis methods include the nonlinearity regression fitting analysis, the exponential smoothing method, the time series analysis method, the gray theory method and the BP neural network method. The deformation tendency after anti-slide pile constructed is also analyzed, which shows that the stability of the landslide increases obviously after anti-slide pile constructed and the deformation is controlled effectively and the measure is effective. The deformation and safety of the landslide in the future is analyzed and predicated according to current analysis, which provides scientific reference for the treatment of the landslide and the safety running of Nanning-Kunming Railway.
