大跨度钢管混凝土拱桥拱肋吊装过程中的线形控制是施工控制的重点和难点,文章论述了线形控制的目的、方法、内容以及影响线形控制精度的因素,并成功应用于湖南益阳茅草街大桥线形控制的工程实践,为其他同类型桥梁的施工和监控提供了参考。
The linear control during the hoisting process of arch rib of long-span CFST arch bridge is the key and difficult point of construction control. The purpose, method and content of linear control as well as the factors influencing the linear control accuracy are discussed in this paper. Control of engineering practice for other similar types of bridges construction and monitoring provided a reference.
