摘要
针对预应力混凝土斜拉桥施工最大单悬臂、最大双悬臂及成桥状态,对结构动力特性及抗风稳定性进行分析,得出了主梁位移及全桥的内力分布情况,并且对抗风稳定性能给予了评价。
Structural dynamic behavior and wind-resistant stability of both most single and double cantilevers as well as whole bridge are analyzed in the construction of the PC cable-stayed bridge. The displacement of the main beam and the internal force distribution of the whole bridge are obtained, and the wind resistant stability of the PC cable-stayed bridge is evaluated.
