In order to evaluate the stress condition and working performance of a box girder bridge in a mining area under the special load of 100T, through static load test, the mechanical properties of the bridge under operating conditions were analyzed and studied. Static load test is the stress test of the main beam under the partial and medium load, finally, the measured results are compared with the finite element result. The results show that under the action of various loads, the check coefficient of the bridge strain and the main tensile strain check coefficient was not exceed the standard allowable value 1, the actual working performance of the structure is very good, the maximum relative residual strain was 8.33%, which are not 20% higher than the standard allowable value, the whole bridge is in the elastic deformation stage, meet with the normal use requirements.
