摘要
为保证重庆某桥加固后运营的可靠性、验证加固后桥梁结构是否满足承载力的设计要求,对该桥进行了静力荷载实验。本文介绍了试验的范围及内容,对控制荷载进行了说明、计算,进而确定了加载的荷载、工况以及加载的顺序。将Midas Civil 2010计算的理论应力和挠度值与实测值进行比较分析,结果表明该桥加固后营运安全可靠,刚度和强度满足设计要求。
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.
