摘　　要：佳木斯松花江公路大桥已经运营超过15年,由于车辆荷载的急剧增加、材质的退化,导致桥梁过早出现了病害。因此,拟对该桥进行维修,加固设计之前要进行桥梁结构的自振特性和强迫振动响应测试,进而揭示桥梁结构振动的内在规律,综合评价桥梁结构的动力性能。Jiamusi Songhua River highway bridge has been operated for over 15 years. Due to rapid increase in traffic load and degeneration of material, diseases have appeared in the bridge prematurely. Therefore, we planned to implement maintenance on the bridge. Tests of natural vibration characteristics and forced vibration response of the bridge structure shall be implemented before reinforcement design so as to reveal the inherent law of bridge structure vibration and to give comprehensive assessment on dynamic performance of bridge structure.
