Design of Reinforcement of Jiahe Bridge

海皮线夹河大桥上部结构为6×22.2m钢筋混凝土T形梁桥。由于运营时间较长、交通量过大等原因,该桥桥面铺装、主梁横向联系等部位出现了严重的外观病害。针对上述情况,对桥梁病害原因进行了分析,提出了相应的加固设计方案。

Superstructure of Jiahe bridge on Hai - Pi line is a T - girder reinforced bridge with 6 × 22.2m length. At deck pavement and transverse connection of main girder etc the brove appearance diseases arise because longer running time and too large traffic volume.
