以浙江省长兴县上莘大桥为对象，采用一般方法建立桥梁分析的初始有限元计算模型，根据桥梁交工验收荷载试验采集的静、动载试验数据，通过建立考虑变形、频率及振型等静、动力信息的多目标函数对初始有限元模型进行修正，得到能够反映桥梁结构真实状况的基准有限元模型。修正后基准有限元模型计算结果与不同静载试验工况下实测数值、动载试验工况下实测振动频率、模态等响应结果进行了对比，结果表明：利用桥梁荷载试验实测数据对桥梁有限元计算模型修正后，有限元计算模型计算结果与荷载试验实测响应结果均能保持一致，利用荷载试验数据修正桥梁结构有限元计算模型是可行的。

With the Shangshen Bridge in Zhejiang province as an example,an initial finite element model is established(developed) under the bridge design drawings,According to the bridge Completion Acceptance of load test collected static and dynamic load test data were collected, considering the deformation, frequency and mode shapes static and dynamic information through the establishment of multi-objective function of the initial finite element model of the amendment, the reference finite element model to reflect the true state of the bridge structure. Amended Baseline Finite Element Model calculations with different static load test conditions, the measured value, measured vibration frequency of the dynamic load test conditions, And the modal response results were compared. The results showed that: the use of bridge load test measured data is limited to the bridge element calculation model correction and the finite element model calculations and load test measured response results are consistent. The load test data correction of bridge structure with finite element model is feasible.
