大型结构试验模型相似理论分析与推导

The Comparability Analysis and Deduction of a Large Structure Test Model

以岳阳洞庭湖大桥模型为例介绍了桥梁结构实验模型的静力和动力模型的相似理论,并用方程分析法和量纲矩阵分析法推论了相似判据以及模态参数的相似比。

This paper is dedicated to the model of three tower cable-stayed bridge of Yueyang Dongtinhu Bridge. The authors applied static and dynamic similarity theory of structure experimentation model and presented the method of associating equation analysis with dimension matrix analysis. The authors also deduced similitude ratio of similitude criterion and mode parameter, and demonstrated rationality of three tower cable-stayed bridge model design of Yueyang Dongtinhu Bridge.
