摘要
以津秦客运专线路桥过渡段路基沉降测试为例,利用BP神经网络方法和灰色系统法研究了路桥过渡段沉降预测问题。计算实例表明,神经网络法和灰色系统法短期沉降预测结果比较准确,简便易行,因而具有广泛的工程实用价值和应用前景。
This article, taking the test on ground settlement at the transition section between bridge and plain track in Tianjin-Qinhuangdao Passenger Dedicated Line for example, studies the prediction of ground settlement of the transition section between bridge and plain track with BP neural network and gray system method. The calculations prove that neural network and the gray system method offer a more accurate result in an easy and effective way ; therefore it is of practical val-ue in engineering and has a broad application prospect.
