摘　　要：青龙桥预应力钢筋混凝土薄壁连续槽形梁是目前国内首次使用于公路交通中的新型桥式,其主桥(26+40+26)m连续槽形梁梁体混凝土采用一次性整体现浇施工,现浇支架的可靠性是施工质量和施工安全的前提。介绍该桥(26+40+26)m连续槽形梁混合支架体系的设计和施工技术。The prestressed concrete thin-walled continuous channel girder of Qinglong Bridge is a new girder type used for the first time for highway bridges in China. The channel girder of the main spans (26 m +40 m +26 m) of the Bridge are concreted in situ in integrity at one time, the reliability of the scaffolding system supporting the girder is thus the essential prerequisite for assuring the construction quality and safety. In this paper, the design and construction techniques for the combined scaffolding system for concreting of the channel girder are described.
