Because the classification indexes is difficult to determine in a specific engineering surrounding rock clsssification , the multiple layer feedforward neural network is used to determine the classification indexes through computating the node contribution rates of input layer and it ' s related formulas are also deduced in this paper . 2 . since the convergence rate of the bp network is slow and node structure of it ' s hide layer is difficult to determine , an improvement of the bp network algorithm and a method to determine the node structure of the hide layer are suggested in this paper 主要的内容有：一、针对在对特定工程围岩进行分类的过程中其分类指标难以确定的问题，提出用多层前馈型神经网络通过计算输入层节点贡献率的手段来确定分类指标的方法，并推导出计算过程；二、针对bp网络收敛速度慢和隐层节点结构难以确定的问题，对bp算法作了改进并给出确定隐层节点数的方法；三、鉴于面向对象的程序设计方法已非常流行，实现了面相对象的bp人工神经网络设计，并建立了围岩稳定性分类的bp网络系统；四、用实现的系统对广州抽水蓄能电站工程进行围岩稳定性分析评价，结果证明人工神经网络方法用于工程地质数据分析有着其他方法不可比拟的优越性。
