首先分析了大跨桥梁抗风理论,以及风对桥梁结构的作用,采用阵风荷载对悬臂施工风荷载进行仿真分析,结果表明,对于刚性较大的连续刚构桥,进行施工阶段抗风分析切实可行,为桥梁悬臂施工抗风提供良好的保障。 Firstly, the theory of wind resistance of long-span bridges and the effect of wind on the bridge structure are analyzed. The gust loads are used to simulate the cantilever construction wind load. The results show that for rigid rigid bridges with large rigidity, Feasible, provide a good guarantee for the cantilever construction of the bridge.
