针对目前较多旧双曲拱桥亟待加固的情况,结合郭坑大桥主拱圈变形较大,出现一些裂缝,采用大型结构分析通用程序,建立双曲拱桥的空间有限元模型进行静力和动力分析,以便准确地对旧双曲拱桥主拱圈进行评估,确定其是否有安全隐患,为将来的旧桥加固与修复提供依据。
針對目前較多舊雙麯拱橋亟待加固的情況,結閤郭坑大橋主拱圈變形較大,齣現一些裂縫,採用大型結構分析通用程序,建立雙麯拱橋的空間有限元模型進行靜力和動力分析,以便準確地對舊雙麯拱橋主拱圈進行評估,確定其是否有安全隱患,為將來的舊橋加固與脩複提供依據。

According to the reinforcement of more old double arch bridges,and combining a large deformation and some cracks on the main arch of Guokeng Bridge, a large-scale structural analysis of the general program,the establishment of space finite element model to the curved arch bridge arch static and dynamic analysis have been made in this paper, in order to accurately assess to some old arch bridges, and determine whether there are security risks,with the hope to provide the reference to the future strengthening and repair of the old arch bridges.
