本文结合辽宁省交通厅资助的重点课题“桥梁质量分级指标及其评价方法研究”对存在损伤的钢筋混凝土梁的抗剪强度进行了试验研究，主要的工作和研究结论如下：1 - at the same time the study analyse the structural system of the index and it's weight with the ahp, and choose soil quality, soil thickness, the content of organic matter, terrain, elevation and the ration of irrigated guarantee as gradation index and choose soil quality, soil thickness, the content of organic matter, terrain, elevation, the ration of irrigated guarantee, the condition of traffic, the distance from the central city, the scatter degree of field, the neat degree of field, loss of water and erosion of soil and land contamination as classification index . at the same time the study emphasize the effect of the condition of ecological condition and environmental contamination
采用层次分析法对该区域农用地分等定级的指标体系及其权重进行了研究，选择表层质地、土层厚度、有机质含量、地形、海拔、灌溉保证率等6项指标参与分等评价，选取表层质地、土层厚度、有机质含量、地形、海拔、灌溉保证率、对外交通状况、距市中心距离、田间道路状况、田块分散度、地面平整度、水土流失、土地污染等13个因子分指标区进行定级评价，强调了生态条件及其环境污染状况在农用地分等定级中的作用。 - 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。 - 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
