上海威宁路桥横向受力分析

上海威宁路桥主桥上部结构为三跨预应力混凝土连续梁结构,横向为双幅主梁连续桥面。桥梁采用纵横向预应力体系,施工方法为悬臂浇筑与满堂支架现浇相结合,横桥向分为两幅进行施工并通过后浇带连为一体。该文根据桥面板,中横梁和边横梁的不同结构特点采用了有针对性的结构形式设计,分别进行横向受力分析,可供相关专业人员参考。

Analysis on Transverse Stress of Shanghai Weining Road Bridge

The upper structure of main bridge of Shanghai Weining Road Bridge is a three-span prestressed concrete continuous girder structure.Its transverse is the two-roadway main girder continuous deck.The bridge uses the longitudinal and transverse prestressing system.Its construction method is the combination of the cantilever cast with full-support cast in site.Its transverse is constructed by two roadways and then connected by the late poured band together.Based on the different structure characteristics of the deck plate,middle transverse girder and side transverse girder,the special designs of structure types are used.The article analyzes the transverse stress,which can be referred for the relative technical members.
