摘　　要：装配式结构的预应力混凝土先简支后结构连续桥梁的施工顺序多样,以4×20 m跨径的装配式预应力混凝土箱梁为例,利用midas Civil分析不同工况下施工顺序对主梁应力影响,并讨论出合理的施工顺序,指导施工作业。The construction sequence of prefabricated prestressed concrete bridge with simple support and continuous structure is diverse.Taking a 4×20 m span prefabricated prestressed concrete box beam as an example,midas Civil is used to analyze the impact of construction sequence on the stress of the main beam under different working conditions,and to discuss a reasonable construction sequence to guide construction operations.
