摘要

The author carried out static load test research on a prestressed concrete rigid frame bridge. Under the action of static load, the most unfavorable section JM3 on the beam body was measured. The stress and deflection values at each measuring point were measured. The results show that the check coefficient of stress and deflection at each measuring point of the box girder does not exceed the standard limit value 1, the relative residual strain or deformation at each measuring point does not exceed the standard limit value 20%, and the overall bearing capacity of the bridge structure meets the normal use requirements of the design load (highway-I class).
