摘　　要：基于磁流变阻尼器的spencer模型,对其进行数值模拟,研究了纵向地震激励下渡槽结构在磁流变阻尼器控制下的地震响应规律。计算结果表明,采用磁流变阻尼器可以有效地抑制渡槽结构在地震激励下的响应,研究结果对大型渡槽结构的抗震设计具有一定的参考价值,为半主动控制用于渡槽结构的抗震设计提供了理论依据。The mechanical model of magneto rheological damper was established,and the numerical simulation of seismic responses of aqueduct under earthquake excitation was performed with magnetorheological dampers. The results indicated that the magnetorheological dampers are effective in reducing the aqueduct response. The results from the present study may serve as a reference base for seismic design of large-scale aqueducts,and provide theoretical basis of aqueduct using semi-active devices.
