摘要
本文首先分析了大跨度斜拉桥临时墩的设置目的,并调研国内主要大跨度斜拉桥临时墩的设置情况。结合中朝鸭绿江界河公路大桥的结构特点讨论了大桥临时墩的设计原则,并对鸭绿江界河公路大桥进行了临时墩设置有限元模拟分析,确定了临时墩需承受的拉压荷载,指导了本桥的监控与施工。
In this paper, the purpose of setting temporary pier of long-span cable-stayed bridge is analyzed and the setting of temporary pier of the main long-span cable-stayed bridge is investigated in China. Combining with the characteristics of the structure of the Yalu river border highway bridge, the design principle of temporary pier is discussed, the finite element simulation analysis of temporary pier of the Yalu river highway bridge is set up to determine the temporary pier under tension and compression loads so as to guide the monitoring and construction of this bridge.
