以土坝测压管水位异常诊断为实例,对反向传播(BP)神经网络进行训练,然后通过典型示例经网络计算生成显式的诊断规则,为专家系统诊断推理时直接调用。该方法是土坝病害诊断知识获取的一种新方法,是对传统知识获取方式的拓展和补充。
Taking the abnormal diagnosis of piezometer water level in earth dam as an example, the BP neural network is trained, and then an explicit diagnosis rule is generated by the typical example through the network calculation, which is called directly for expert system diagnosis reasoning. This method is a new method for acquiring knowledge of earth dam disease diagnosis, which is to expand and supplement traditional knowledge acquisition methods.
