Construction Analysis and Monitoring Technology of Reverse Fink-Type Truss Bridge
From the perspectives of theoretical analysis,numerical simulation,wind tunnel test,construction monitoring and operation monitoring,this paper deeply explores the structural stress characteristics,construction difficulties and coping strategies,dynamic performance and vibration control measures of Hangzhou Canal Bay Pedestrian Bridge(15.9+150+15.9)m,the currently world's longest reverse Fink truss bridge.The results show that the measured data of construction monitoring(including linear,stress,cable force,etc.)are highly consistent with the results obtained by numerical simulation analysis,which fully verifies the rationality of the established construction plan.At the same time,the monitoring data during the operation period are consistent with the finite element calculation results,indicating that the bridge structure has reached the preset design goals.Wind tunnel tests and numerical analysis were used to verify the wind resistance and seismic performance of the bridge.It can provide reference for the construction and development of reverse Fink truss bridge.
