摘 要: 以广州南沙凤凰二桥为工程实例,采用Midas/Civil有限元计算软件进行全桥仿真计算。分析了主腹拱连接方式对葵花型拱桥结构受力和主腹拱抗裂性能的影响,为葵花型拱桥的设计、施工提供参考。计算结果表明:主腹拱铰接时腹拱圈受力较主腹拱固结时有利,并且主腹拱铰接对减少腹拱圈裂缝宽度也更为有利。
关 键 词: 土木建筑结构;受力性能;有限元;葵花型拱桥;裂缝

Abstract: Taking the 2rd Fenghuang bridge in Nansha, Guangzhou as engineering example, the simulation calculation of the whole bridge was obtained using Midas/Civil finite element calculation software. Furthermore, we analysed the influence on the main abdominal arch bridge connection type of sunflower arch bridge structure and its impact on the main abdominal arch crack resistance, which provided a reference for sunflower type arch bridge design and construction. The analysis results show that compared with consolidating the main arch and the abdominal arch, the hinging of them not only contributes to the force of the arch ring, but also contributes to reducing the cracking wide of the arch.
Key words: civil architecture; mechanical properties; finite element; sunflower arch bridge; crack
