摘要
通过坝陵河大桥的节段模型风洞试验获得了主梁的静力三分力系数、主梁的颤振特性以及识别了主梁的8个颤振导数,并对试验结果进行了详细的分析,其分析评价的结果可用于指导该桥的设计与施工,也可为同类桥梁提供参考。
Through the wind tunnel test for the sectional mode of Baling River Bridge, the static three-component coefficients and the fluttering characteristics of the main girder of the Bridge were obtained, the eight fluttering derivates of the main girder were identified and the results of the test were analyzed in detail. The analysis and evaluation of the results can be used to guide the design and construction of the Bridge and can also serve as reference to the bridges of similar kind.
