摘要
为评判已建成桥梁的工作性能,进行静动荷载试验是行之有效的方法之一。近年来,下承式系杆拱桥病害问题逐渐引起桥梁设计者的重视。通过对某下承式系杆拱进行静动荷载试验研究,将实验数据与理论数据与规范进行对比,结果表明该桥梁技术状况良好,结构达到设计荷载公路-Ⅱ级的承载力及刚度要求。
This paper studied the static and dynamic load test of a tied arch bridge and compared the experimental data and theoretical data and specification. The results showed that the bridge was in good technical condition, the structure met the bearing capacity and stiffness requirements of designing load highway levelⅡ.
