摘要
通过预制薄壁U梁与传统箱梁的设计比选,详细阐述了预制U梁结构在城市轨道交通工程设计时的结构形式采用和需要注意的结构要点。结合青岛13号线轨道交通工程,分析了预制薄壁U梁结构方案的优缺点,经过技术、经济、景观等多方面比选,为今后同类的高架桥工程上部结构选型提供了依据。
According to the design comparison of prefabricated thin-wall U-shaped beam and the traditional box girder, the article sets forth the structural style used and the structural gist for attention of the prefabricated U-shaped beam structure in the engineering design of urban metro. Combined with Qingdao Metro Line 13 Project, the article analyzes the advantages and disadvantages of prefabricated thin-wall U-shaped beam structure scheme. The comparison of technology, economy, landscape and etc. can provide the basis for the selection of superstructure of the similar viaduct projects.
