摘要
义乌丹溪大桥为国内首座斜靠式系杆拱桥,为确保桥梁各构件在成桥后能满足设计时的受力状态,并考虑安装施工的方便性和经济性,选用了标准器拖拉法进行钢主梁安装。详细介绍了膺架的设计、施工情况及利用移位器进行拖拉的安装技术;提出了几点技术保证措施。
The Yiwu Danxi Bridge is the first inclined tied-arch bridge in China. Standard dragging was applied in installation of the main steel girders so that all structural members of the completed bridge were able to follow the designed stress requirements and construction installation was convenient and economic. Design and installation of the falsework and the shifter-dragging technique and the technical guarantee measures are introduced in detail in the paper.
