摘要
对混凝土刚架拱桥进行了荷载试验及检测数据分析,并运用大型有限元程序Midas进行了仿真分析,通过多种工况下桥梁变形和内力实测值的比较、实测动力学曲线的频谱分析,以充分了解桥梁结构的力学性能,为桥梁的安全使用提供依据。
The paper makes loading test on RC steel frame arch bridge and analyzes the inspection data, it makes simulation analysis by using the large finite element procedure Midas. It also compares deformation and actual internal force under different circumstances, analyzes spectrum of actual dynamics curve, so as to fully understand the mechanism of bridge structure, as well as provide accordance for safely use of bridge.
