大型公路钢箱梁正交异性桥面板工地接头即箱梁节段之间的连接,过去均采用全焊或高强度螺栓连接。各国实桥运营经验表明,这两种连接方式各有不足。所以,随着施工技术的不断进步,钢桥面板工地接头构造细节也再演变。介绍了大型公路钢箱梁正交异性桥面板工地接头构造细节的演变,并通过两个足尺试件的静载和疲劳试验以及有限元分析,证明正交异性桥面板工地接头采用焊栓连接具有足够的刚度、承载力和耐久性。
Large highway steel box girder orthotropic bridge panel site joints that box girder section of the connection between the past are all welded or high strength bolts. The actual operation experience of all countries shows that these two connections have their own shortcomings. Therefore, with the continuous improvement of construction technology, the construction details of steel bridge panel site also evolved. This paper introduces the evolution of the structural details of the joint of the steel orthotropic bridge deck with large steel box girder. Through the static and fatigue tests and the finite element analysis of two full-scale specimens, it is proved that the joint of the orthotropic bridge deck with welded joints Has sufficient rigidity, bearing capacity and durability.
