The Use of BP Neural Network in the Landslide Prediction of Three Gorges Reservoir

Abstract

Landslide prediction was one of the important tasks in the monitoring and early warning of the Three Gorges reservoir. On the basic of the BP neural network which was combined with the algorithm model, we took the typical Baishuihe landslide in Three Gorges reservoir for example. With the use of GPS monitoring data in surface displacement and its predisposing factors which was reservoir level, rainfall and so on, we built BP neural network prediction model. The monitoring of data recent years was used in the training and validation of the network .The results show that the BP neural network prediction model prediction can be used in the prediction of landslide deformation and the accuracy is high.
