摘要
采用神经网络ＢＰ算法，对城市公路网络进行了震害预测，通过计算实例验证效果较好，为进一步进行城市公路网络系统的震害预测研究奠定了基础．
The artificial neural network BP method is used to investigate the prediction of the earthquake calamity for the city highway network. It is proved by calculating the living example that the method is a better one. And it estableishes a good base for further study of the earthquake calamity of the city highway network system.
