摘要
连续刚构桥现在已发展成一种常见桥型,特别在山区,高墩与挂蓝悬臂施工,使得连续刚构桥更具优势。线型监控是连续刚构桥监控的重点,而预拱度又是线型的重要内容。以正在建设的某公路刚构桥梁为实例阐述连续刚构桥预拱度的计算问题,并应用有限元软件进行计算分析。该桥的顺利合拢,表明该桥的线型控制是成功可行的。
Continuous rigid frame has now developed into a common characteristic bridge, especially in the mountains, high piers and cantilever construction, make the advantage of long span continuous rigid frame bridges. Linear monitoring is the focus of long span continuous rigid frame bridges monitoring, and the pre-camber is the important content of the line. This paper based on the engineering examples continuous rigid frame arch the calculation problem of degrees, and using finite element analysis software for calcula- tion. This bridge successfully, shows that the bridge＇s line type control is succeeding.
