摘　　要：文中以某座空腹拱桥为例,为了解该桥运营期间结构现状受力状况,借助有限元模型计算结合静动载试验等方法,对受力性能进行了分析。结果表明,结合桥梁外观检查及静动载试验结果,在设计荷载作用下,桥梁现状上部结构满足结构性能要求。该试验方法与数据分析评价对同类拱桥的试验具有一定借鉴意义。Taking an open spandrel arch bridge as an example,in order to understand the current structural stress status during the operation of the bridge,the force performance was analyzed by finite element model calculation combined with static and dynamic load test,and the results showed that combined with the results of bridge appearance inspection and static and dynamic load test,the current superstructure of the bridge meets the structural performance requirements under the design load.The test method and data analysis evaluation have certain reference significance for the test of similar arch bridges.
