通过理论模型分析和室内振动台试验验证，揭示淤积砂层不仅有吸收库水地震反应能量的吸能作用，而且存在惯性放大效应，其相应频率随淤积砂层厚度变化．
Through the theoretical model analysis and indoor shaker test, it is revealed that the silt layer not only has the energy absorption effect of seismic energy of reservoir water, but also has the effect of inertial amplification. The corresponding frequency varies with the thickness of the silt layer.
