摘要
宜昌长江大桥主桥采用大跨度连续钢构柔性拱的组合桥型,结构新颖,施工难度大,在施工中采用了新工艺、新材料以及新技术。介绍了主梁施工方案、施工步骤以及主要施工技术特点和技术难点。
The main spans of Yichang Yangtse river bridge are designed as a composite structure with continuous rigid frame and flexible arch. The structure is unique in design, however, the construction is very difficult for which quite a few new workmanships and techniques and materials may be required. In this paper, the construction schemes and procedures are introduced as well as the principal technique features and difficulties.
