摘　　要：本文主要对某高速公路空心板梁桥的上部结构拼宽进行分析研究。对于空心板梁桥,原则上采取相同截面的空心板梁进行拼接,但鉴于空心板自身缺陷及运营过程中存在的病害情况,需对拼宽梁型进行比选研究。本文提出预制双T梁方案与空心板进行对比,研究表明预制双T梁方案在技术经济上具有优势。In this paper,the super structure of a hollow slab girder bridge is analyzed and studied.For hollow slab bridges,hollow slab Bridges with the same section should be splicing in principle.However,in view of the defects of hollow slabs and the existing diseases in the operation process,it is necessary to carry out a comparative study on the split-width beam types.In this paper,the prefabricated double T beam scheme is compared with the hollow plate.The research shows that the prefabricated double T beam scheme has advantages in both technical and economic aspects.
