某四跨变截面预应力混凝土连续箱梁桥采用悬浇挂篮施工工艺,本文针对该工艺下的挂篮结构进行了设计研究,将贝雷拼装体系引用到挂篮设计中,本文对该挂篮构件设计进行了详细的说明,并对该挂篮在各级预压荷载条件下进行了有限元理论分析,实测值与理论计算吻合较好并成功运用到了该桥施工中。
A four-span prestressed concrete continuous box girder bridge cross-beam suspension basket construction technology, the paper design for the craft under the basket structure, the Beilei assembly system is referenced to the design of the hanging basket, the paper linked to the hanging The design of the basket is described in detail, and the finite element analysis of the basket under the conditions of preload at all levels is carried out. The measured values agree well with the theoretical calculation and are successfully applied to the construction of the bridge.
