摘　　要：随着经济的发展,桥梁建设尤其是大跨度桥梁的建设应用越来越广,连续梁因其自身优点在大跨度桥梁中最为常用,因此如何解决好大跨度连续梁的施工问题变得尤为迫切.本文结合京沪高速铁路全线最大跨度连续梁——跨南运河(80+128+80)m连续梁底座板施工,通过对其单元划分等施工技术进行研究,为相关工程提供有益经验.With the economic development,bridge construction,especially the construction of large-span bridges is used more and more widely.Due to its own advantages,continuous beam is commonly used in large-span bridges.Therefore,how to solve the problems in the construction of large-span continuous beam becomes more urgent.Combining with the construction of base plate of continu-ous beam with maximum span of Beijing-Shanghai high-speed railway,which is cross the South Canal by 80＋128＋80 m,the construction technology of its cell division is studied in this paper, which may provide useful experience for the related proj ects.
