既有T形刚构桥无损检测及承载力评定

Nondestructive testing and bearing capacity evaluation for T-type bridge

介绍了既有T形刚构桥无损检测和承载力评定的方法,其中理论值的计算用Midas进行建模分析,为使模型与实际工作情况更加接近,考虑了桩土共同作用的影响,根据评定结论提出了加固维修建议,从而确保结构的耐久性。

Describes the methods of nondestructive testing and bearing capacity evaluation for T-type rigid frame existing prestressed concrete bridge, using the element analysis program Midas to calculated the theoretical value, in order to make the model closer with the actual situa- tion, considered the interaction of pile-soil in the article. According to the evaluation result, some advice on the intensification and maintenance is pointed, in order to ensure the durability of the structure.
