文章对某铁路桥上简支箱梁在吊装落梁过程中端头面上出现较大裂缝进行分析,发现形成裂缝的主要原因是:在落梁过程中两侧吊杆的不同步松放导致梁体的扭转和施工过程中荷载偏差系数较大。相关计算结果可供同行在进行同类设计受力分析时参考借鉴。
In this paper, the analysis of larger cracks in the end face of a simply supported box girder on a railway bridge during lifting and lowering of the beam found that the main reason for the formation of cracks is that asynchronously releasing Body torsion and load factor in the construction process larger coefficient. Relevant calculation results can be used as a reference for peers in the same type of design stress analysis.
