以国内已建拱坝体形参数为基础，以ＢＰ神经网络方法为手段，建立了拱坝体形参数近似优化的人工神经网络模型．借助该模型不仅可以为拱坝体形优化快速提供高质量的初始可行解，而且可为中、小拱坝体形设计直接提供近似最优解．
Based on the body shape parameters of arch dam in our country, an artificial neural network model of approximate optimization of body shape parameters of arch dam is established by BP neural network method. The model can not only provide high-quality initial feasible solutions for arch dam shape optimization quickly, but also provide approximate optimal solution directly for shape design of medium and small arch dams.
