摘　　要：运用压路机-桥梁耦合振动的分析方法,为研究某预应力连续空心板桥沥青混凝土桥面铺装压实过程中,压实设备对桥体振动的影响,采用不同的压实设备进行实时对比测试,给出振动压路机与振荡压路机施工过程中对桥体产生的振动加速度的对比测试数据,结果显示振荡压路机对桥体的施工振动影响明显小于振动压路机。With the method coupling the vibrations of a compactor and the bridge, vibratory influences of the compactor to the bridge body during asphalt concrete paving operation are studied for the prestressing forced, continuous and hollow-core slabs bridge. Various compactors operations are tested comparatively in real time. Comparative test data of the bridge vibratory accelerations from the operations of a vibratory compactor and a oscillating compactor are presented and the results show that the operation impact from a oscillating compactor to the bridge body is significantly smaller than that from a vibratory compactor.
