摘要
结合上海长江隧桥B4标段105 m钢-混凝土叠合箱梁施工实际,介绍大跨度箱梁整孔运架一体吊架系统的主要构造、系统功能和工作原理,在沿海施工条件恶劣地区,该方法有较好的实用性。
In the light of the construction of the 105-m span steel and concrete composite box girders of Contract B4, Shanghai Changjiang River Tunnel and Bridge Construction Project, this paper presents the principal structural formation, functions and working principles of the hoisting frame system designed for both the transportation and erection of the full long span box girders. The system has very good practical application to large engineering structures in the costal areas where the construction conditions are hash.
