在役简支T梁桥承载力分析研究

Analysis and Research on the Bearing Capacity of Simply Supported T-beam Bridge in Service

为了考察辽宁省某在役T梁桥在运营过程中的实际技术状况、工作性能、实际承载能力,对该桥进行了系统的外观检测、无损检测、荷载试验等,依据检测结果,计算各项折现系数,实现对桥梁的承载能力分析,从而确定桥梁现有承载力是否与其荷载等级相匹配,为该桥日常养护及维修加固提供理论依据。

In order to investigate the actual technical status,working performance and bearing capacity of a T beam bridge in service in Liaoning province. In this paper,the appearance inspection,nondestructive inspection and load test of the bridge are carried out,and the discount coefficients are calculated according to the test results,so as to analyze the bearing capacity of the bridge and determine whether the existing bearing capacity of the bridge matches its load grade. It provides theoretical basis for daily maintenance and maintenance of the bridge.
