Experimental Research on Dynamic and Static Load of Semi-rigid Continuous Box Girder Bridge
Dynamic and static load test of bridge is an important method to test the safety of bridge structure,which can accurately evaluate the mechanical performance and actual working state of bridge structure.According to JTG/T J21-01-2015 Load Test Methods for Highway Bridge,dynamic and static load tests were carried out on the main bridge of Taolaizhao Large Bridge to test the deflection,strain and dynamic characteristics of the bridge structure,compared and analyzed with the theoretical values,the results show that the bridge is in the elastic stress state,the strength and stiffness meet the design requirements,the dynamic response and dynamic characteristics are good.
