摘要
北京丽泽路人行天桥采用斜拉索式设计,结构新颖。介绍了针对斜拉索人行天桥施工过程中的难点和关键点,阐述了控制主梁安装前后拱度、塔柱安装垂直度、拉索张拉的次数和力值三个方面的施工工艺。通过项目验收,可以看出采用此工艺施工质量优良,为类似工程施工提供了经验,具有实际工程应用价值。
Beijing Lize Rd. pedestrian bridge is of new structure and designed by stayed-cable type. The difficulties and key points of the stayed-cable pedestrian bridge are introduced. There are construction techniques from three aspects in this paper, camber before and after main beam installation, verticality of tower pier and the dragline tensioning times & force values. Through the project test, the construction by stayed-cable type is of excellence and application, which provides reference values for similar projects.
