摘要
以《公路沥青路面设计规范》（ Ｊ Ｔ Ｊ０１４ － ９７） 为依据，根据神经网络理论，提出采用三层 Ｂ Ｐ 网络近似计算柔性路面三层弹性层状体系理论弯沉的方法。通过大量的计算与验证，训练好的 Ｂ Ｐ 网络精度高、速度快、泛化能力强，且易于实现，可以应用于工程设计与验算。
Based on “Specifications for design of highway asphalt pavement” (JTJ014-97) and the theory of neural networks, a new method to calculate the deflection of three-layer elastic layered system with a three-layer BP neural network is presented in this paper. Through a great deal of computations and checks, the trained BP neural network is accurale, speedy, expansive and easy to operate. The network can be used in the engineering design and check.
