大跨度钢结构桥的施工技术

Construction Technology for Long-Span Steel Structure Bridge

上海大芦线航道整治工程一期(临港新城段)19标Y6桥属于大跨度钢结构桥。以此为例,介绍了大跨度钢结构桥安装中的关键施工技术。该工程采用了先梁后拱的施工方法,保证了钢结构施工的顺利进行与完成,为类似工程的施工提供了经验。

Section 19 Bridge Y6 of Da-Lo channel renovation project 1 in Shanghai （a period of Lingang New City Section） is a steel structure bridge with large span. Using the project as an example, this paper introduces the key construction technology in installation of steel structure bridge with large span. This project adopts the construction method of ＂first beam then arch＂, ensuring the success of steel structure construction, providing reference for similar constructions.
