    摘要:

    在以大跨、轻质、高强为标志的现代桥梁结构中,箱梁与缆索承重桥梁结构是两大重要的分支。为此,笔者系统综述了其相关理论的2019年研究进展[1],具体包括波形钢腹板箱梁理论、传统箱梁空间分析理论、多塔悬索桥缆鞍相互作用、缆索承重桥梁极限承载力及UHPC技术在缆索承重桥梁中的应用5个方面,为了及时掌握相关的研究动态,对2020年关于以上内容的研究进行梳理与总结,并增加了缆索承重桥梁体系的最新发展。研究结果表明,结构体系的持续创新为精细化箱梁与缆索承重桥梁理论的不断深化提供了契机。

    Abstract:

    Modern bridges is symbolled by long-span, light-weight and high-strength, of which the box girder and cable-supported bridges are two important parts. To that point, the corresponding research progress in 2019 of the related theories is summarized by the authors[1], including the theory of the new box girder with corrugated steel webs and traditional box girder, the interaction between cable and saddle in multi-tower cable bridge, the ultimate load capacity of cable-supported bridges, and application of UHPC technology in cable-supported bridges. A review is made to further understand the research trends of the above five aspects in 2020. In addition, the recent development of the cable-supported bridges is discussed. It is concluded that as the emergency of the new structural forms the refined analysis theory of box girder and cable-supported bridges have new opportunities to extend.
