With the development of the prestressed concrete construction technology, more and more prestressed concrete box girder bridges have arisen in our nation. However, after construction, the appearance of the cracks on some of these bridges takes some unfavourable influence on the structures. In common sense, we should take some methods to strengthen and repair these bridges as soon as possible, but because of the civil pecuniary condition, we can't repair all the broken bridges in one time. Therefore a scientific estimation must be made about the load-carrying capacity of these prestressed concrete box girder bridges with cracks, so that we can decide which bridge should be repaired firstly.

随着预应力施工技术的不断进步，我国已拥有越来越多预应力混凝土箱形梁桥，这些桥在使用一段时间后，有很大一部分箱梁出现了大量的裂缝，这些裂缝的出现对桥梁结构将产生不利的影响，所以应尽可能的对其进行加固修补，但限于国内实际经济状况，我们不可能一次性全部进行加固改造，需要对在役的这些开裂后的预应力梁桥的工作状态特别是承载力做出科学的评判，以便区分轻重缓急，优先实施。

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。
