Abstract
Taking the main bridge of the shuidong bridge in Youxi country of Fujian province as background, this paper develops the static characteristic analysis and static load test study on long-span prestressed continuous rigid frame bridge with V-shaped pier. By the analysis and comparison between the measured data and FEA results, it evaluates the working condition of the bridge. The results show: Firstly,each evaluation indicator tested meets the requirements of “Test methods for large-span concrete bridges” Secondly, the strain efficacy coefficient of measured points in top plate of each control section is within 0.65∼0.74, and that of the measured points in bottom plate is within 0.64∼0.73, the residual strain of the measured points is less, therefore, the safety stock of the bridge is sufficient, and it is on the flexible working condition basically; Finally, the measured value and the theoretical value of deflection curves along the longitudinal bridge is compatible, the efficacy coefficient of vertical deformation is within 0.55∼0.85, and the severity of the practical structure is more.
