摘要
以某钢管混凝土系杆拱桥为研究对象,对其进行成桥的静荷载试验,同时借助桥梁结构专用程序MIDAS CIVIL对其进行分析。通过理论计算和试验实测数据的对比分析,验证该结构的强度、刚度是否满足设计要求,动力特性是否满足行车安全的需求。试验表明:该结构刚度和强度均满足设计要求,且具有良好的动力特性。
Taking a concrete filled steel tube bowstring arch bridge as the study object,the static load test of finished bridge is carried out for this bridge.At the same time,this bridge is analyzedby the special software MIDAS CIVIL of bridge structure.The comparative analysis of theoretical calculations and experimental measured data can verify whether or not the strength and rigidity of this structure meet the design requirements,and the dynamic characteristics meet the driving safety.The results show that the strength and rigidity of this structure meet the design requirements,and the dynamic performance of the structure is good.
