In this study,a long-span cable-stayed bridge with single tower and mixed beam was subjected to static load test. By simulating the actual stress of the bridge,the deformation,stress and displacement of the bridge were measured and analyzed. It was found that the deflection,mid-span torsion,pier settlement and stress test results met the current requirements,and the main girder and tower of the bridge showed good deformation performance,and the bridge structure quality was good. According to the test results,the bridge can be inspected and maintained regularly to ensure the stability of the bridge structure.
