| 摘 要： | 简单介绍大跨桥梁施工控制，并以温福铁路连续梁桥为背景，应用桥梁专用软件分析各施工阶段的累计节点位移、主要截面内力及应力的变化。基于MATLAB平台开发桥梁施工控制神经网络预测立模标高程序。仿真计算结果表明：该程序在学习训练后，能预测后续各节段的立模标高并具有良好的精度和鲁棒性。

| Abstract: | Firstly,the construction control in large-span bridge construction is briefly introduced.Taking the Wenfu continuous beam railway bridge as engineering background,according to the calculation results by the professional bridge software,the total nodal displacements of the construction phases,the change of the internal forces and stress at the main sections under dead loadings are analyzed.Finally,based on the platform of Matlab,the ANN program to predict the elevation of the mould plate for bridge construct... |
