For the study on the bearing capacity test of bridge,the paper presents the study of the bridge test design and data analysis joining the project example in Beijing. The bridge load experiment detects and evalutes the bearing capacity,transverse joint perfomance,the local deformation,coping and abutment bearing capacity. The results shows that the various test indexes of the bridge are normal,the bridge situation could meet the requirement of the normal usage and safety transport. But considering that the local of the bridge has damge,some advice is given to repair the damge. The idea and methods of this paper can be used on the similar projects.
