| Abstract: | The bridge load test is the most effective and most direct and the most convincing method to evaluate the bridge bearing force. The paper conducted a static load test on a multi span prestressed concrete bridge, and firstly introduced the test methods and process, and then measured the deflec- tion, stress, fracture of the control cross sections, and finally obtained some valuable conclusions. |
