九江大桥T梁维修加固效果评定

Evaluation on Reinforcing Effect of T-beam of Jiujiang Bridge

桥梁运营期间,因受到各种因素的影响,桥梁结构将产生各种损伤或局部破坏。对九江大桥跨中44#孔T梁进行静载试验,以评价T梁结构维修加固的效果,掌握维修加固后T梁的实际承载能力,为桥梁采取下一步措施提供基础数据和依据。

During the bridge operation,the bridge structure will be affected by various factors,and there will be various damages or local damages for the bridge structure. In this paper,a static load test on the 44th-span T-beam of Jiujiang Bridge across the middle span has been conducted to evaluate the repair and reinforcing effect of the T-beam structure,to grasp the actual bearing capacity of the T-beam after maintenance and reinforcing,which could provide basic data and basis for the measures taken next to the bridge.
