在许多公路板梁桥中,主梁和横梁连接处都产生疲劳裂缝,本文介绍了影响主、横梁连接处生成裂缝的结构参数。研究了大阪市阪神高速公路干线上板梁桥的结构参数和在主、横粱连接处生成裂缝之间的关系,发现混凝土板由于运行车辆而产生的交形对主、横梁连接处生成裂缝有很大的影响。
In many highway girder bridges, the fatigue cracks occur in the joints between the main girder and the transverse girder. This paper introduces the structural parameters that affect the cracks generated in the connection between the main girder and the transverse girder. The relationship between the structural parameters of the girder bridge on the Hanshin Expressway in Osaka City and the cracks generated at the junction of the main girder and the girder was studied. It was found that the intersections of the concrete slab with the main girder and the transverse girder generated by running the vehicle generated cracks Great impact.
