| Abstract: | In order to make sure the reliability of the bridge in Chongqing after being reinforced and verify whether the reinforced bridge can meet the requirement of bearing capacity,load test for the bridge have been carried out.This paper introduces the range and content of the load test and illustrates the controlled load.Then,the size,the order and the working condition of the load are confirmed.Use the calculation software-Midas Civil 2010 to calculate the theoretical value of deflection and stress and compare them with the practical value.The result shows that the reinforced bridge is safe and reliable for the daily use and its stiffness and strength meet the devised requirement. |
