不同施工方案连续梁桥受力分析

On stress analysis of continuous girder bridge with various construction schemes

结合连续梁桥满堂支架现浇施工和分节段支架现浇施工受力存在一定差异的情况,对(40+60+40)m预应力混凝土变截面连续箱梁桥两种施工方法进行了计算分析,得出了几点结论,为以后类似桥梁施工方案选择提供参考。

Combining with some differences between the full house support cast-in-place construction of continuous girder bridge and segmental support construction, the paper calculates and analyzes the two construction methods for （40 ＋ 60 ＋ 40）m prestressed concrete variable crosssection continuous girder bridges, and achieves some conclusions, so it provide some reference for the selection of construction schemes for similar bridges.
