| 摘 要： | 建立了大跨度斜拉索输油管桥模型实验的相似条件，并以某大跨度管桥为例，采用两种不同的边界条件，对某大跨度斜拉索输油管桥固有振动进行了模型实验，通过实验，测得到了管桥的前几阶自振频率并与有关计算结果进行了比较，比较结果验证了文中的实验方法的可靠性，提出的实验方法可以用于预报类似柔性结构体系的固有振动频率。

| Abstract: | The long span cable stayed pipe bridge are used broadly in the oil engineering. The resemble conditions of the model experiment for long span cable stayed pipe bridge are set up, and the long span cable stayed pipe bridge is taken as example.With the different boundary conditions, the model experiment of natural vibration for long span cable stayed pipe bridge was carried, and the first natural frequencies of the pipe bridge were determined through the experiment.The experimental results is reliable by comparison with other calculated results. The method presented in this paper can be used to predict the natural frequencies of the similar flexible structural system. |
