既有立交桥上钢箱梁吊装
摘要：利用钢箱梁抗弯截面大、正负弯矩抵抗能力相近的特性；通过将墩间钢箱梁接长、临时加长、纵向非对称装载、运输等措施；使用在墩位附近移动都受到限制的跨墩龙门吊完成了在既有立交桥范围内的钢箱梁吊装作业。避免了在桥上或桥边使用汽车吊或履带吊作业时对既有桥梁结构安全的不利影响和对铁路、公路上运行车辆干扰的影响。
关键词：钢箱梁、悬臂、挂臂、吊装

Overpass on both hoisting steel box
Abstract: The bending of steel box-section, positive and negative moment resistance similar characteristics; through the pier between the steel box will take a long, long interim, asymmetrical vertical loading, transport and other measures; spaces near the pier in the use of mobile Are subject to restrictions on cross-pier Crane completed within the framework of the existing overpass of the steel box hoisting operation. Avoid the use of motor vehicles on the bridge or bridge crane or suspended operations of the existing bridge is structurally safe and the adverse effects of rail, road vehicles run interference.
Key words: steel box girder, cantilevered, upper arm, hoisting
