摘要
桥梁结构的顶升及托换,会对桥梁的结构姿态及构件应力等产生较大影响、可能对桥梁结构安全性造成影响。以福州地铁某盾构区间穿越桥梁、桩基托换工程为背景,通过开展最不利工况分析、信息化施工,确保顶升施工的安全和桥梁结构安全可控,为后续地铁穿越类似桥梁提供借鉴。
The lifting and underpinning of the beam structure will have a greater impact on the structural attitude and component stress of the bridge,and may affect the safety of the bridge structure.Taking the crossing bridge and pile foundation underpinning project in a shield section of Fuzhou Metro as the background,through carrying out the most unfavorable condition analysis and information monitoring,the safety of jacking construction and the safety and control of the bridge structure are ensured,and provide a reference for subsequent subway crossing similar bridges.
