Abstract：
Taking the retrofit engineering of a three span continuous girder bridge as an example, the method of the external prestressing technique, which is suitable for the project, is selected by comparing all kinds of the reinforcement methods of the old bridges. Through the bridge test, the mechanical behavior of the continuous beam bridge is analyzed. The test results show that the structure is safe and reliable, which can meet the need of the engineering practice, and the reference is provided for the similar reinforcement project in the future.
