In order to understand the dynamic property of extradosed cable-stayed, built up its plane continous rigid-frame model and compared with each other, concluded that the former is more complex due to the remarkable coupling effect of cable, pylons and box-girder. The dynamic property of box-girder decide the dynamic property of the bridge, whose whole structure is comparative rigid. This paper indicated that the bridge is not attribute to flexible structure, because its basic free vibration cycle is more shorter than the cable-stayed bridge.

为了更好的理解矮塔斜拉桥的动力特性，还建立了平面梁单元的连续刚构模型，并与平面梁单元的矮塔斜拉模型进行了对比分析，结果表明，矮塔斜拉模型由于索、塔、梁的高阶振型耦合显著，其振型较连续刚构复杂，灵江大桥的动力特性主要由主梁的动力特性决定，其结构整体刚度较大，基本自振周期较斜拉桥短，不属于柔性结构。

After being prefabricated, they will be carried to the point, and installed on the bridge. Seated very close to each bridge, prefabrication sheds are responsible for prefabricating girder boards and culvert cover boards. Dadoes are set up according to the number of girder boards. Two joist barrows and one 315KVA power transformer are fixed in prefabrication shed .
