| 摘 要： | 以一座在建的葵形拱桥为例,采用Midas软件建立了全桥仿真模型,分析了主腹拱不同的连接方式及拱顶段不同的结构形式对葵形拱桥结构受力性能的影响。计算结果表明:对于葵形拱桥结构的受力,主腹拱铰接优于刚接,拱顶段采用实腹式优于叠合梁式。

| Abstract: | Taking a sunflower arch bridge under construction for example,Midas software is used to build a full bridge model,and to analyze the influences of different connection modes of main arch and different structure forms of vault section on structure stress of sunflower arch bridge.The results indicate that,as for the structure stress of sunflower arch bridge,the articulated connection of main arch is better than the rigid connection,and the solid-web of bridge vault section is better than the laminated beam. |
