摘要
详细介绍了BP神经网络的基本原理和建模方法 ,指出BP人工神经网络模型克服了模型必须是基本观测量的线性和非线性组合的局限 ,并具有很强的自适应性和容错性 .将BP模型应用于大坝空间位移分析 ,编制了BP神经网络模型程序 ,并对湖北某土石坝空间位移进行分析 ,得到了较好的拟合和预报 .
The basic theory and modelling method of BP neural network are described. The BP model can overcome the shortcoming of that the conventional models must be the combination of linearity and non_linearity. The model has high ability of self_adaptability and characteristics of accepting the error. The thesis applies BP model to analyze spatial displacement of an earth_rock dam in Hubei Province, and compiles the program of BP model. The results show that the model has good effectiveness.
