    摘要:

    针对风驱雨作用下桥梁主梁的颤振问题，依据风驱雨作用和主梁振动特点，给出了分别考虑雨滴冲击和表面积水后的降雨相似关系，并探讨了其选取原则。选取大跨度桥梁较常采用的典型断面，通过节段模型试验模拟了风驱雨对主梁断面的颤振导数和颤振发生过程的影响。试验结果表明：主梁断面的颤振气动导数随雨强的变化无明显规律，各导数的变化量值相当，随风速增加，降雨引起的导数变化有所加大，但基本没有改变其随风速变化的整体趋势，试验雨强120 mm/h时，模型颤振临界风速会有20%~30%左右的提高，但考虑雨强相似比后可以认为降雨对桥梁主梁的风致颤振失稳特征的影响基本可以忽略。

    Abstract:

    Regarding the problem of bridge girder's flutter under influence of wind-driven rain, the rainfall similarity laws are firstly established in terms of raindrop impact and surface ponding respectively, according to the characteristics of wind-driven rain and bridge main girder's vibration, besides, the selection principle is also discussed. Then, several typical main girder sections, which are frequently used in long-span bridges, are selected as examples to investigate the influence of wind-driven rain on flutter derivatives and flutter occurrence process by sectional model tests. Results show that there is no significant regularity between the flutter aerodynamic derivatives of the main girder and the rainfall intensity, as the variation of each derivative is almost the same. Comparatively, the variation of derivative caused by rainfall is increased with the wind speed. However, the general variation trend of the flutter aerodynamic derivatives with wind speed is not changed. When the test rain intensity is 120 mm/h, the critical wind speed of the flutter model raises about 20%~30%. Considering the similarity law proposed in this paper, the effect of rainfall on wind-induced flutter characteristics can be ignored.
