摘　　要：以杭州湾跨海大桥70m箱梁为实例,介绍了大型整体预制箱梁的运输架设技术。对箱梁陆上纵横移、海上运输及整孔架设中的机具设备和施工中的关键技术作一阐述,并采用有限元程序计算了箱梁在运输各状态中的受力及变形。Take 70 m span precast box girder of Hangzhou Bay Bridge for an example, transportation anderection techniques of the huge precast box girder are introduced. A review of equipment and key techniques about moving, transportation as well as erection of box girder is given in this paper. Based on the finite element procedure, the stress and deflection of box girder in the transporting case are calculated.
