高墩大跨连续刚构桥悬臂施工阶段抗风安全性研究

摘要

Aim at the west region of long-span continuous rigid frame bridge with high-rise piers structure,calculated based on engineering of the bridge design wind speed wind resistance,in the structure of the maximum double cantilever stage,under the action of the static wind load of the structure of the internal force of a detailed analysis and flutter research,draw some valuable conclusions.%针对西部地区的高墩大跨连续刚构桥结构，推算出依托工程的桥址处抗风设计风速，在结构的最大双悬臂阶段，对静阵风荷载作用下结构的内力进行了详细的分析和颤振研究，得出了一些有参考价值的结论。
