Application of GM-ENN composited model in forecast of landslide deformation
Deng Jihui · Yangtze River · 2011
Aiming at the poor applicability of present landslide deformation forecast model,based on the view of system theory and time series principle,the landslide displacement was divided into tendency item and deviation item.Through the extraction of the time series tendency item by grey systematic model and simulation of complicated non-linear relation of time series deviation item by evolutionary neural network,the GM-ENN composited model was set up for landslide deformation research.The composited model was used in the deformation forecast of Baishuihe landslide in TPG area.The research result shows the composited model has strong modeling ability and high accuracy.
