| 摘 要： | 为了降低桥梁结构的高度,1995年在哈尔滨修建了第一座预应力宽钢箱梁桥,随着车辆荷载和流量的增加,该桥的桥面等部位出现了较为严重的损伤。为评定预应力宽箱梁桥的工作性能,我们于2006年对该桥进行了静载试验。通过两种工况的跨中加载、测试和理论分析,证明该桥工作性能良好,能够满足设计承载力的要求,同时也验证了预应力宽形钢箱梁在大跨桥梁结构应用的可行。

| Abstract: | In order to reduce height in the bridge structure,in 1995 the first wide prestessed steel-box-girder bridge was built in Harbin.Along with the increasing of vehicles load and volume of traffic,many serious damages appeared in the surface of this brideg.In order to evaluate the operating performance about it,we have carried on the dead load experiment to this bridge in 2006.Through the loading test and the theoretical analysis about two kind of operating modes,it was proved that operating performance for thi... |
