Analysis of Static and Dynamical Test of Anqing Changjiang River Highway Bridge

Anqing Changjiang River Bridge(510 m-span cable-stayed bridge) is taken as an example for introducing the method of static and dynamical test of cable-stayed bridge including the deflection test of the beam and the tower,the change of tension of the cables,and the stress of the beam and the tower under static loads.The natural vibration of the structure is tested,and the impact of the passing vehicles is analyzed under dynamical loads.The test results indicate that the beam and tower work at elastic state under the normal applying load.The design of the structure is rational,and has enough strength and stiffness,satisfying the design requirement.
