上承式钢管混凝土拱桥拱肋吊装施工技术研究

Study on deck-type CFST arch bridge rib hoisting construction technology

本文结合一座上承式钢管混凝土拱桥的设计概况,通过对拱肋吊装系统的总体设计,说明了吊装方案的特点并详细阐述了拱肋吊装的施工技术,完善了无支架缆索吊装系统,为拱桥的建造提供了一些技术借鉴。

The paper combines the design overview of a deck-type CFST arch bridge, through the overall design of the rib hoisting system, describes the characteristics of hoisting plan and elaborates rib hoisting construction technology,perfects non-support cable erection system,and provides technical reference for bridge construction.
