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 cant 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。
