Abstract:

On the basis of MATLAB programming language, BP neural network and stepwise regression are applied to predict the deformation at monitoring point No. 27 of Xijin dam. Furthermore, the combination prediction method of BP network and stepwise regression is put forward and the prediction results of 3 methods are compared. The research shows that it is feasible to apply BP neural network to dam deformation analysis and prediction. In addition, the combination method improves the scientific quality to choice deformation factors. The combination method is prior to the method of stepwise regression in prediction result and it is worth to further study.

Key words: dam deformation prediction, BP network, stepwise regression
