摘　　要：V型墩连续刚构桥刚度大,受力合理,能有效的降低主梁的建筑高度,能在一定程度上增加主梁的跨越能力,以荆州市城北快速路跨荆襄河V型墩连续刚构桥为研究对象,对V型墩柱施工中合理的支架搭设、分段及浇筑顺序进行分析,通过对方案优化、过程监测等手段圆满地完成了桥梁的施工,提高了施工质量和施工效率,该方法在V型墩刚构桥施工中具有一定的借鉴价值。The V-shaped continuous rigid-frame bridge with the large rigidity and reasonable stress can effectively reduce the building height of the main girder,and increase the spanning capacity of the main girder to some extent.Taking the V-shaped pier continuous rigid-frame bridge crossing Jingxiang River in Chengbei Expressway of Jingzhou City as the study object,the reasonable sequence of bracket erection,segmenting and pouring in the construction of V-shaped piers are analyzed.The bridge construction is successfully completed by the scheme optimization,process monitoring and other means to enhance the construction quality and construction efficiency.This method has some referring values in the construction of V-shaped pier rigid-frame bridges.
