摘　　要：在立交通道桥的维修改造设计中,采用预制钢梁代替传统混凝土现浇板梁的设计,可保证快速实施,最大限度地减少断交施工周期,消除交通隐患。该文以王顶堤立交1号通道桥的上部结构更换钢梁设计为例,对此进行论述。In the design of maintaining and reconstructing the passage bridge of the interchange,the prefabricated steel beam is used to replace the traditional concrete cast-in-site plate beam able to guarantee the high-speed implementation,and to decrease the construction period without the traffic in the minimum limit and to remove the hidden damage to the traffic.Taking the design of steel beam replacing of the superstructure for No.1 passage bridge of Wangdingti Interchange as an exampie, the article discusses it.
