摘要
以东海大桥、杭州湾跨海大桥等四座跨海大桥为背景,针对箱梁架设过程中采用的精确定位技术进行阐述,并提出最优的跨海大桥预应力混凝土整孔预制箱梁的精确定位施工方法,对今后同类型桥梁架设定位方法具有指导意义。
Taking four sea-crossing bridges including East Sea Bridge and Hangzhouwan sea-crossing Bridge as the background, the paper de- scribes the accurate positioning technique used in box girder erection, and puts forward optimum accurate positioning construction method of full- span prestressed concrete box girder of sea-crossing bridge, which has certain guiding meaning for similar bridge erection positioning in future.
