摘　　要：从桥梁减隔震的机理出发,以我国正在建设的某轨道交通槽形梁桥为工程背景,采用非线性有限元及车桥耦合振动分析理论,综合研究了轨道交通槽形梁桥采用减隔震装置前后的抗震性能和轨道交通车辆的走行性。研究结果表明,采用减隔震装置可明显改善轨道交通槽形梁桥的抗震性能,并能确保轨道交通车辆日常行车的要求。A constructing rail transit bridge with U-shaped girder in a place of China is regarded as the engineering hackground of this paper. The seismic performance and train running characteristics of U-shaped girder bridge, which may be with or without seismic isolation device, are discussed synthetically. The result of the research shows that the seismic performance of rail transit U-shaped girder viaduct with seismic isolation device is improved obviously and the train running characteristics of the bridge is also ensured.
