摘要: 中承式钢管混凝土系杆拱桥施工,由于主桥结构复杂、技术含量高、施工难度大,要求在施工过程中对全过程 进行施工控制。通过对缆索吊装系统吊装行车道边梁、龙门吊机吊装行车道内梁和汽车吊机吊装人行道梁等3个 阶段的施工控制,确保了大桥建成后线形符合设计要求,结构受力合理,为相似桥梁的施工监控提供借鉴。

Abstract: As the main bridge structure is of complexity,hish technology content and construction dificuhicuhy,the construction of concrete.filled steel tubular tie.bar arch bridge requires construction control in the whole process of construction. Though the monitoring of carriageway edge beams lifted by hoisting cable hoisting system,machine and car lanes lifted by gantry crone an d sidewalk beams lifted by the cran e hoisting,it is ensured that the bridge alignment meets the design requirements after completion and the structure stress is rational,which provides a reference for the similar bridge construction monitoring.

Key words: concrete-filled steel tubular tie-bar arch bridge, bridge alignment, structure force, construction control
