| 摘 要： | 大跨度预应力混凝土连续箱梁施工的线形控制是施工过程中的难点,如何根据施工监测所得的结构参数真实值进行施工阶段的仿真分析,确定出每个悬臂浇筑阶段的立模标高,保证成桥后桥面线型、合拢段两悬臂端标高的相对偏差不大于规定值,是文章论述的主要问题。

| Abstract: | Linear control is a difficulty in large-span box beam bridge construction.The main problems discussed in the paper is how to make simulation analysis of the construction process according to the monitoring parameters and then to make clear the formwork erection level for every cantilever casting and to make sure the linear differential values along the bridgedeck and between the cantilever elevation of connecting segments are less than the standard values. |
