下承式拱梁组合结构桥梁荷载试验研究分析

Analysis on Load Testing of Through Arch-beam Composite Structure Bridge

以福州市某下承式拱梁组合结构桥梁为工程背景,通过静动载试验对该拱桥结构性能进行分析,结果表明:下承式拱梁组合结构应用于市政桥梁工程,能达到设计强度及变形能力的要求,但运营过程中需加强吊杆索力监控。

In this paper, taking a through arch-beam composite structure bridge in Fuzhou as the engineering background,its structural performance is analyzed by applying static and dynamic load test,the results show that the through arch-beam composite structure can be used in municipal bridge engineerings as it satisfies the requirements of design strength and deformation;But the suspender cable force must be monitored in the operational process.
