加固后T梁桥标准化荷载试验检测方案设计

Design of standardized load test inspection scheme for strengthened T-beam bridge

公路桥梁在服役运用的过程中,由于各种原因导致主要承重构件受损,不得不进行结构的加固以恢复和维持原有的结构承载力,加固后的桥梁按照规范规定需要进行试验检测合格后方可通行。与新建桥梁相比较,加固后的桥梁在新建桥梁检测的内容基础上,还需进行其他参数的检测,以一加固后的高速公路T梁桥为例,开展加固桥梁试验检测方案的设计,为同类工程提供参考。

During the service and operation of highway bridges,the main load-bearing components were damaged due to various reasons,so the structure had to be strengthened to restore and maintain the original structural bearing capacity.The strengthened bridge can only be operated after passing the test according to the specifications.Compared with the newly-built bridge,the strengthened bridge needs to be tested for other parameters on the basis of the content of the newly-built bridge detection.This paper takes a reinforced highway T-beam bridge as an example to carry out the design of the strengthened bridge test detection scheme,providing reference for similar projects.
