摘要
以芜湖市三环路青戈江大桥为例,详细介绍了主桥上、下部结构设计要点,并采用基于平截面假定的平面杆系分析方法对主梁纵向静力结构进行了分析计算,为今后变截面预应力混凝土连续箱梁桥的设计、施工提供了参考借鉴。
Taking Qinggejiang bridge on Sanhuan road in Wuhu city as an example, the paper specifically introduces the upper and lower bridge structure design points, analyzes and calculates the vertical static structure of the main beam by applying horizontal truss analysis method based on plane cross-section assumption, which has provided some guidance for the design and construction of prestressed concrete box girder with various cross-section.
