| 摘 要： | 采用悬臂施工的大跨预应力混凝土连续刚构桥在合龙前的最大双悬臂阶段为整个施工过程中的最不利抗风状态，但还需考虑由于不对称施工而由风载产生的不利影响。结合灵江大桥的施工，对几种不利风荷载情况进行风载静力分析，并采用节段模型风洞试验进行风振分析，讨论了变截面箱形桥梁的抗风特性。

| Abstract: | Long span continuous P.C. rigid bridge using cantilever construction is in adverse of stage of anti-wind on the largest double cantilever stage before closure, but adverse effects of wind due to non-symmetric construction are analyzed. Static analysis is taken for several wind loads with the Lingjiang Bridge construction. Wind vibration is also studied by wind tunnel test of section model, and anti-wind characters of box girder with non-uniform cross-section are discussed. |

| Keywords: | continuous beam bridge rigid frame bridge wind load wind tunnel test dynamic structural analysis |
