改进的BP网络在嵌岩桩承载力预测中的应用

The application of an improved artificial neural network to forecasting the bearing capacity of rock-socketed piles

本文提出了用改进的 BP网络对嵌岩桩承载力进行预测的新方法 ,并编写了相应的训练程序。实例计算表明 ,改进的 BP网络算法比一般的 BP模型结果误差小、收敛快 。

A new method of using improved BP network is presented to make a training program. The calculations show that the improved BP network is precisier and has a quick effect compared with the common BP model. And the method of artificial neural network is effective in forecasting the bearing capacity of the rock-socketed piles.
