摘　　要：采用等价粘弹性模型,对勐野江面板堆石坝进行了地震峰值加速度为0.146 g的二维地震响应计算分析,比较全面地了解了面板堆石坝坝体的加速度、动位移和永久变形分布规律,为坝体结构设计、坝体抗震稳定性的确定提供了重要依据。The equivalent viscous-elastic model was used to calculate and analyze 2D seismic responses of the Mengyejiang Concrete Faced Rockfill Dam under the conditions of earthquake peak acceleration of 0.146g, which makes us understand completely the acceleration ,dynamic displacement and permanent deformation distribution law of dam . body and provides important basis for the determination of the structure design and seismic stability of dam body.
