新坝东路分离式立交桥桥墩的检测与维修加固

Detection and Maintenance Reinforcement on Piers of Separation Overpass Bridge in East Xinba Section

连徐高速公路新坝东路分离式立交桥2#墩柱裂缝严重,经对桥墩裂缝进行详细检测,明确了桥墩裂缝产生原因,在桥墩内力验算基础上提出维修加固方案和施工方法,以期为类似桥梁的维修加固提供参考.

Serious cracks occurred in 2# pier of the separation overpass bridge in east Xinba section of Lianyungang-Xuzhou expressway. Detailed detection on the pier cracks resulted in determination of their causes. Based on the internal force checking calculations of the pier, this paper suggested the maintenance reinforcement plan and construction methods, so as to present references for maintenance reinforcement on similar bridges.
