The bridge load test is an important means to evaluate the completed performance, construction quality and structural bearing capacity of the bridge structure, including determining the dynamic load test to determine the natural frequency, damping ratio and vibration mode of the bridge structure or structure, so as to determine the structural rigidity. The quality is an important factor to determine the basis. However, for the dynamic characteristics measurement method of the upper bearing arch bridge, the specification does not give a detailed detection method or recommendations. Combining with the analysis results of the field test data of the upper bearing arch bridge, this paper obtains a more accurate arrangement of test points.
