분폭식강상량%횡량수력%방안비선
separated steel box girder%stress in cross beams%method comparison and selection
以嘉绍大桥分幅式钢箱梁安装为背景，通过建立有限元计算模型，对横梁受力进行分析和比较，对钢箱梁悬臂分幅安装和整幅安装进行比选。最终选定横梁受力合理且过程更为安全的分幅安装方法。
以嘉紹大橋分幅式鋼箱樑安裝為揹景，通過建立有限元計算模型，對橫樑受力進行分析和比較，對鋼箱樑懸臂分幅安裝和整幅安裝進行比選。最終選定橫樑受力閤理且過程更為安全的分幅安裝方法。

Taking the Jiaxing-Shaoxing River-Crossing Bridge as the background,which is a separated steel box girder bridge, according to the finite element model, we analyzed and compared the stress in cross beams, made the comparison between the unilaterally method and the united method for the cantilever installation. We selected the unilaterally method because of more reasonable stress and the more secure progress.
