荆州市城北快速路工程V型墩施工研究

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。

Study on V-shaped Pier Construction of Jingzhou City Chengbei Expressway Project

The multiple V-shape pier used in steel structure bridge have advantages such as large rigidity ,reasonable stress,reducing the building height of the main beam,Increasing the spaning capability of the main beam. In this paper, Multiple V-shape pier steel structure bridge of Jingzhou north city expressway crossing Jinxiang river was selected as experiment object. The article makes an analysis of supporter erection,segmented pouring,pouring sequence in building V-shape pier. It finally improves construction quality and efficiency through scheme optimization and process monitoring.
