Static load test and analysis on completed deck arch bridge of large-span reinforced concrete

摘要

Based on the requirements of load test technique on existing long-span concrete bridge, a deck arch bridge of large-span reinforced concrete was taken as the engineering background and the emulation analysis was done by building the bridge model using the finite element software Midas/Civil. The values of stress and deflection were measured and calculated. The results of the test show that the static working performance of the arch bridge is fine, the stiffness and load capacity meet the requirements of the design and the construction quality is good. It can provide references for the bridge design of the same type, learning about the actual working condition of the bridge and evaluating the working performance and load capacity of the bridge structure in the serviceability limit states.
