BP神经网络在基坑工程变形预测中的应用

结合工程实例,针对基坑开挖过程的变形特点,应用BP神经网络和基于粒子群优化算法的BP神经网络对基坑支护结构的变形进行预测,并对两种方法预测结果进行比较分析。结果表明,基于粒子群优化算法的BP网络的泛化预测性能要优于BP网络,预测深基坑地下连续墙结构水平位移更有效。

Application of BP neural network in the foundation pit deformation prediction

Combining with specific engineering project,this paper aimed at the degeneration characteristics of the excavation process of foundation pit,applied BP neural network and BP neural network based on particle swarm optimization algorithm to predicted the deformation of foundation pit shoring structure,and analyzed comparatively the results with two methods.The results showed that particle swarm optimization algorithm based on BP network generalization performance preceded BP network prediction,prediction of d...
