摘要
南通丁堡河大桥为钢管系杆拱桥,文章以该桥更换吊杆施工监控为例,通过有限元计算,对其吊杆更换过程中应力、索力和变形的全过程进行监测,提出监控要点,以供类似工程参考。
Nantong Dingbao River Bridge is a steel tubular bowstring arch bridge. Taking the construction monitoring of sus- penders replacement of the bridge as an example, the stress, cable tension and deformation are monitored in suspenders re- placement process by FEM, which could be taken as reference for similar project.
