遗传算法BP神经网络在变形监测中的研究

摘要

The author introduced basic concepts and theories of BP neural network and genetic algorithm. Then, the author minutely expounded two neural network models of BP neural network optimized by genetic algorithm, and deeply analyzed data forecast of two models in monitoring of horizontal displacement of foundation pit. Finally, the author put forward BP neural network models optimized by genetic algorithm had better forecast effect.%　　介绍了BP神经网络和遗传算法的概念和基本理论，详细阐述了遗传算法优化的BP神经网络和BP神经网络这两种神经网络模型，深入分析了两种模型在基坑水平位移监测的数据预报，指出了遗传算法优化的BP神经网络模型具有更好的预测效果。
