某预应力混凝土组合箱梁桥损伤检测与加固

DAMAGE DETECTION AND REINFORCEMENT OF A PRESTRESSED CONCRETE COMPOSITE BOX GIRDER BRIDGE

文中以某建设期30m跨预应力混凝土组合箱梁桥出现横隔板开裂现象为例,针对该桥横隔板开裂进行专项外观检测,对病害产生原因进行了分析并针对病害产生原因进行加固处理,取得了较好的效果,为类似桥梁病害的检测及加固提供参考。

This article takes the case of the diaphragm cracking of a 30 m span prestressed concrete composite box-girder bridge in a certain construction period as an example.A special appearance inspection is carried out for the cracking of the diaphragm of the bridge. Furthermore, the causes of the disease are analyzed and the causes of the disease are reinforced. Finally, the paper has achieved good results and provides a reference for the detection and reinforcement of similar bridge diseases.
