摘　　要：以某座预应力钢筋混凝土连续梁桥为例,先介绍了预应力钢筋混凝土连续梁桥的基本情况以及该桥的振动测试,然后建立符合桥梁当前状态的有限元模型,最后,通过实测和计算的结果比较分析了钢筋混凝土连续梁桥的动力特性。结果表明:动力测试与分析可对有限元模型修正,有利于桥梁健康评价和养护维修。Taking a prestressed concrete continuous beam bridge as an example,the basic situation and the vibration test of the bridge were introduced firstly.Then,a finite element model which accords with the current state of the bridge was established.Finally,the dynamic characteristics of the prestressed concrete continuous beam bridge by the comparison of the measured and calculated results was analyzed.The results show that the dynamic test and analysis can modify the finite element model,which is beneficial to bridge health evaluation and maintenance.
