Abstract :
The paper presents all operation procedures of a vibration testing method for effective tension in box-girder bridge, as well as its application situation in more than thirty long-span PC box-girder bridges. And all the key points have been succesfully used to control the construction quality of rebar vertical prestress system. Moreover, the succesful practice of using the testing method to enhance quality reveals the reliability of rebar vertical prestress system for long-span PC box-girder bridges.
