摘    要:为改善大坝安全监控BP神经网络模型易陷入局部极值的问题,引入萤火虫算法,用来获取BP神经网络的连接权值和阈值的初始值。依据大坝安全监测数据,借助改进后的BP神经网络,实现大坝安全监控模型的构建和安全状况预测。实例验证结果表明,改进模型较常规BP神经网络模型的训练效果更稳定,预测精度更高。该方法具有一定的实用价值。

关 键 词:大坝安全    监控模型    BP神经网络    萤火虫算法    小波包分解

Dam Safety Monitoring BP Network Model and Its Application Based on Firefly Algorithm
Abstract:BP neural network easily falls into local minima when it used to dam safety monitoring model. In order to improve this problem, the firefly algorithm was used to calculate the initial value of connection weights and thresholds for BP neural network. Based on the monitoring data of the dam, the safety monitoring model of dam was established and its safety condition was predicted with the improved BP neural network. Example proves that the improved model has advantages in both training result and prediction accuracy compared with the conventional BP neural network model. The method has practical value.
Keywords:dam safety  monitor model  BP neural network  firefly algorithm  wavelet packet decomposition
