刚架拱桥长细杆件施工技术

Construction Technology of Long Slender Members of Rigid-frame Arch Bridge

以武汉绕城公路机场互通1号桥为例,介绍了刚架拱桥长细杆件的施工技术,包括长细杆件预制、移运及拱片安装,重点介绍长细杆件中拱腿的重叠法预制、移运方法及拱片安装的施工工序,为装配式刚架拱桥拱片的预制、安装积累了一定的经验。

By the example of No.1 airport interchange bridge of highway around Wuhan city,the authors present the long slender members of rigid-frame arch bridge construction technology,including prefabrication,conveyance and installation of long slender members,especially overlapped prefabrication,conveyance of long slender members and installation procedures of arch.Prefabrication and installation experiences of pieces of arch in fabricated rigid arched bridge have been accumulated.
