，Application of BP Neural Network Model in Dam Deformation Monitoring

LI Shao-hua, DONG Zeng-chuan(College of Water Resources and Environment, Hohai University, Nanjing, Jiangsu 210098, China) ?

Aiming at the limitation of traditional method of statistical model, BP neural network model is advanced for the analysis of dam deformation monitoring data in this paper. Structure and algorithm of BP neural network model are introduced together with the normalization of sample data. The application of this model in Heihe Jinpen Reservoir shows that its precision is prior to that of statistical model.
