摘要
文章依据规范确定飞龙岛大桥桥位处的抗风设计参数,对主桥最大单悬臂施工状态的动力特性进行了分析,确定了主梁的三分力系数取值,并通过风荷载计算与静风稳定性数值分析,验证了该桥在施工阶段的抗风性能。
By following the rules,the article develops wind resistance parameters of Feilong Bridge.It also analyzes the dynamics of the main single-hand cantilever,finalizes the mechanic coefficients,and verifies the wind resistance through tests.
