摘要
脊骨梁结构用于高架桥,具有一定的优势,已开始逐步应用并引起关注。介绍了脊骨梁结构发展的概况,通过脊骨梁结构在天津国防路高架桥的应用实践,总结了该工程总体设计的特点,结构形式设计中的关键技术以及施工工艺的重要控制点。应用结果证明该梁型可满足各种荷载等级高架桥的使用功能,值得推广。
The application of the spine girder structure to the viaduct has some merits, which is popularizing and drawing more attention. Based on the engineering practice in adopting that structure on Guofang Rd. Viaduct, Tianjin, a brief description is hereby given of its development, with a summary of the overall design features, the key techniques in the structural design and control points during construction. Results show that it can satisfy viaducts with all load grades, and is worth popularizing.
