Forecast for landslide based on Optimum Grey model
Xianfu Li · Journal of Wuhan Institute of Technology · 2012
The sliding time is the key to forecast landslide,and landslide prediction model is the core of landslide prediction.Grey prediction model was applicable and effective because of the ambiguity and grey uncertainty of landslide.Based on grey system theory,the modeling process,precision examination and higher-order optimization on residual error were studied.According to effective monitoring data selected,the sliding model was studied in light of an engineering example.By comparison with traditional GM model and optimized GM model,the latter had high analog precision.The sliding time was predicted,which showed that the time was so early to play a role in landslide warning.Through an analysis of the prediction model,some significant and helpful conclusions were obtained,which may be a reference to landslide prediction for future.
