以江西省宜春市老袁河大桥（刚架拱）加固提载工程为实例,依据大桥的病害及其成因,重点研究了拆除并更换部分弦杆加固的技术,以恢复刚架拱的强度与整体性。该桥还同时应用了在大、小节点、斜撑和主拱腿拱脚处外包钢筋混凝土、重建桥面铺装等加固与改造技术,可供出现类似病害的刚架拱桥维修加固参考和借鉴。
以江西省宜春市老袁河大橋（剛架拱）加固提載工程為實例,依據大橋的病害及其成因,重點研究瞭拆除併更換部分絃桿加固的技術,以恢複剛架拱的彊度與整體性。該橋還同時應用瞭在大、小節點、斜撐和主拱腿拱腳處外包鋼觔混凝土、重建橋麵鋪裝等加固與改造技術,可供齣現類似病害的剛架拱橋維脩加固參攷和藉鑒。

In this paper,Yichun City,Jiangxi Province Lao Yuan Bridge（arch frame） set out reinforcement works to mention as an example,based on the bridge of the disease and its causes,focusing on the removal and replacement of part of the chord reinforcement techniques to restore the arch frame strength and integrity.The bridge has also applied in large and small nodes,leg braces and the main arch at the outsourcing of reinforced concrete arch,reconstruction and transformation of bridge deck and other reinforcement techniques,for similar diseases frame reference for arch repair and reinforcement.
