摘　　要：对某高架桥分岔处局部应力进行仿真分析。按照实际施工过程,考虑最不利计算荷载,根据平截面假定,分别对钢梁单独受力和钢-混凝土组合梁两种工况进行计算。结果表明分岔处整体受力良好,安全储备大。The analysis of the local stress for a viaduct branch is introduced. Following the process of construction, considering the worst loads, according to the assumption of plane section, the steel girder alone and the composite girder are computed respectively. The results indicate that the branching has a good global condition and sufficient emergency safety capacity.
