摘　　要：上海长江隧桥105 m钢-混凝土组合箱梁重2 300 t,采用"天一号"吊船海上长距离运输85海里到桥位架设,运输风险大,架设精度要求高、难度大,介绍大跨度组合梁的运输、架设技术。The 105-m span steel and concrete composite box girders, weighing 2 300 t each piece, for the Shanghai Changjiang River Tunnel and Bridge Project were transported by sea by Tianyi Lifting Vessel at a long distance of 85 nautical miles to the Bridge site where the girders were then erected by the Vessel. The risk of transportation of the girders in such a condition was great, the precision requirements for erection of the girders were high and the erection was difficult. In this paper, the techniques for the transportation and erection of the long span composite box girders are dealt with.
