A five span continuous rigid frame bridge in Zhejiang province employs two separate type two tank four-chambered structure box girder and V pier. To evaluate its actual performance and bearing capacity under test load and construction quality, made to check bridge span structure static strain, static deflection and dynamic load test is done to check bridge span structure dynamic strain, natural vibration frequency, impact coefficient. A comprehensive evaluation is given to the bridge structure load performance.
