| Abstract: | The paper test the state of a completed trafficway bridge. The test include static load test and dynamic load test,and the load is provided by heavy truck. The vertical deflection value,distribution of stress（ strain）,cracks of the components,impact coefficient of the control section, dynamic characteristics of the bridge can be obtained by the test. Test results show that the carrying capacity and working state of the bridge meet the demands of design and regular service. |
