德胜大桥T型刚构加固工艺及加固后监控成果分析

Reinforcement Technology of T-shaped Rigid Frame of Desheng Bridge and Analysis of Monitoring Results after Reinforcement

以佛山市德胜大桥为工程研究背景,分析该桥病害状况并介绍体外预应力的加固工艺,然后通过MIDAS/FEA建立仿真计算分析比较理论值与实测值,最后分析加固后桥梁监控成果,监控结果表明:该桥通过增加T型刚构体外预应力的加固方法,能很好地增加其承载能力。

Taking the Desheng Bridge in Foshan City as the engineering research background,the disease status of the bridge is analyzed and the reinforcement technology of external prestress is introduced.Then,the simulation calculation is established through MIDAS/FEA to compare the theoretical value and the measured value,and finally the monitoring results of the bridge after reinforcement are analyzed.The monitoring results show that the bridge can well increase its bearing capacity by increasing the external prestressing method of the T-shaped rigid frame.
