上饶市信江大桥拓宽提载设计与静荷载试验

On the widening-increasing load design and static load test on Xin river Bridge in Shangrao city

结合上饶市信江大桥拓宽提载工程实例,对大桥主要结构病害的原因进行了分析,采用桥梁结构计算程序MI-DAS建立有限单元模型对其进行了验算,介绍了拓宽提载设计方案和静荷载试验方案,达到了预期的目标。

Combining with the widening-increasing load project of Xin river Bridge in Shangrao city as a case,it analyzes the causes of the bridge disease.It makes a check and calculation by adopting the bridge structure calculation program MIDAS to establish a finite element model,and introduces widening-increasing load design program and static load test program,so as to achieve the desired objectives.
