摘要
根据天津市子牙河立交桥的工程实践,介绍大曲率混凝土葵形拱桥模板设计方案、拱圈施工段划分、拱圈施工顺序,以及拱部施工控制要点、防开裂措施,为类似工程提供借鉴。
In light of the engineering practice of Ziya River Overpass in Tianjin City, this paper introduces the template design scheme of the big-curvature concrete sunflower-type arch bridge, the division of the arch ring construction section, the sequence of the arch ring construction, as well as the construction keys and cracking prevention measures in the arches. It can be of reference to similar projects.
