Taking a high-pier and large-span asymmetric continuous rigid frame bridge as engineeringbackground, the bearing capacity of the bridge is evaluated by comparing the measured results with thefinite element calculation results through static and dynamic load tests. The results show that under staticload test conditions, the stress calibration coefficient of the girder body is between 0.44 and 0.89,whichindicates that the overall strength of the bridge span structure is good; The deflection calibrationcoefficient is between 0.42 and 0.87,which indicates that the overall stiffness of the bridge spanstructure is good. After unloading, the relative residual stress and deformation do not exceed 20% of thespecifications, indicating that the girder body is basically in elastic working state. Under the conditions ofdynamic load test, the impact factor of A—A section measured in barrier-free driving test ranges from0.041 to 0.049, the real impact factor of B—B section ranges from 0.031 to 0.050, and the impactfactor of C—C section ranges from 0.042 to 0.044. The impact factors of A—A and C—C sections areless than the design value. It shows that the structure will not produce too much impact under the normaldriving state of the design load, and the impact factor of B—B section is close to the design value. In thefuture bridge operation, the observation and maintenance of B—B section of the bridge should bestrengthened. The measured natural frequency of the bridge structure is greater than the theoretical calculated value, and the measured damping ratio of the bridge is in the normal range. The bearingcapacity of the bridge meets the design （highway-Ⅰclass） bearing requirements.
